Description
Technical field
The utility model relates to a kind of medical instrument, specifically a kind of novel centrum functional pincers.
Background technique
Osteoporosis is a kind of systemic, metabolic bone systemic disease, and pathological characters reduce for bone amount, bone is fine
Structure is destroyed, bone brittleness increases, and bone strength decline, osteoporosis centrum compression fracture is most common caused by osteoporosis
Fracture form, with China human mortality aging, senile osteoporosis and its it is caused fracture have become reduce the elderly
Quality of life a key factor.In addition, in contrast, the elderly's Tumor incidence is also higher, certain metastases are extremely
Pathologic vertebral compression fracture caused by spinal vertebral also happens occasionally.
When compression fracture of vertabral body problem occurs for discovery, it would be desirable to which identifying it is osteoporotic vertebral compression
Fracture or pathologic vertebral compression fracture, targetedly to take different therapeutic schemes.
For pathologic vertebral compression fracture, carrying out pathological tissue biopsy is the goldstandard for judging whether metastases,
And conventional aspiration biopsy usually requires to introduce puncture needle into lesion repeatedly, but since structure is complicated for vertebral anatomy, neoplastic lesion
Blood supply is abundant, therefore aspiration biopsy mode is easy to cause and the complication such as pneumothorax, hemotoncus, injured nerve root and Implantation matastasis occurs.
Though may also reduce the accuracy of biopsy simultaneously although the generation of complication can be reduced by reducing puncture needle biopsy number, cause
It can not judge to cause the true cause of fracture problem.So lacking a kind of latter problem when not only can be reduced materials, but also energy at present
The instrument of high-effect high-quality materials.
Utility model content
The purpose of the utility model is to provide a kind of novel centrum functional pincers, it is easy to make in a manner of existing needle puncture biopsy to solve
The problem of at complication such as pneumothorax, hemotoncus, injured nerve roots.
Purpose of the utility model is realized as follows:
A kind of novel centrum functional pincers comprising have binding clip, claw beam and handle three parts, the binding clip is by hinged fixation
Clamp and active clamp are constituted；The claw beam is made of the pull rod that the pincers with hollow lumen are managed and are set in pincers pipe；It is described
Handle is made of hinged fixed handle and flexible handle；
The leading portion of the fixed clamp is plier portion, and back segment is the interconnecting piece with hollow lumen, the connection of fixed clamp
Portion end is connect with described pincers pipe one end；The lower end of the fixed handle is handheld terminal, and upper end is the connection with hollow lumen
Portion, the interconnecting piece of fixed handle are connect with the pincers pipe other end；
The pull rod is arranged in the hollow lumen of fixed clamp, pincers pipe and fixed handle, the end of pull rod and movable hand
The upper end of handle connects, and the front end of pull rod and active clamp rear end are hinged.
Novel centrum functional pincers described in the utility model, on the occlusal surface in the plier portion of fixed clamp and active clamp
Offer the groove for grabbing and accommodating organization material.
Novel centrum functional pincers described in the utility model are provided in the articulated shaft two sides of fixed handle and flexible handle
The first limit block machine and the second limit block machine on fixed handle；The height of the first limit block machine makes the grips pincers
Occlusal surface is closed completely when folder is engaged with the active clamp, and the height of the second limit block machine makes the fixed clamp and institute
Stating occlusal surface maximum when active clamp opens is in 90 ° of subtended angles.
The beneficial effects of the utility model are: in treatment centrum osteolytic bone tumour and Osteoporotic Vertebral Compression Fractures
Minimally Invasive Surgery (percutaneous vertbroplasty) operation in, the centrum functional pincers of the utility model can pass through institute in surgical procedure
The work sleeve used draws materials to centrum tissue while Minimally Invasive Surgery.When being operated inside centrum, the binding clip of opening
It can rotate 360 °, pincers are carried out to the tissue in each orientation in centrum inside and are taken, so that pathologic sampling is more abundant, obtain higher
The pathological material of quality.The approach that functional pincers carry out pathologic sampling simultaneously is carried out in working column, avoids puncturing institute repeatedly
Centrum is brought to close on the related complications such as spinal cord, blood vessel, peripheral nerve injury and Implantation matastasis.In addition, the utility model is obtaining vertebra
Manufacturing cavity while body sample, bone cement is filled in first in the areola of functional pincers manufacture, with the push-in of bone cement,
From cavity to slow disperse around, it is uniformly distributed.Artificial cavity makes the reduction of centrum internal pressure, subtracts so that bone cement injects pressure
Small, Dispersed precipitate is more uniform, to effectively reduce the severe complications such as bone cement leakage.

Specific embodiment
As shown in Figure 1, centrum functional pincers provided by the utility model are mainly made of binding clip, claw beam and handle three parts,
Wherein, handle and claw beam part angle are 90 ° ~ 180 °, preferably 120 ° ~ 150 °.Claw beam part is made of pincers pipe and pull rod 3, is clamped
The consistent tubular body with hollow official jargon of thickness before and after Guan Kewei, and operation and observe when using for convenience, it can also be such as Fig. 1 institute
Show, the second half section is thicker overstriking section 4, and front half section is thinner contraction section 5, and pull rod 3 is set in pincers pipe.Binding clip part knot
Structure is as shown in Fig. 2, binding clip is made of hinged fixation clamp 6 and active clamp 7；The front of fixed clamp 6 is plier, and rear portion is
Tubular body with hollow official jargon is fixed at the occlusal surface 8 of the plier (and plier of active clamp 7) of clamp 6 and offers approximation
The groove 9 of triangle centrum, for grabbing and accommodating organization material, the rear end of fixed clamp 6 and the Front-end Design of pincers pipe are
One, 3 front end of pull rod is protruded into the tubular body of fixed clamp 6, hinged with the end of active clamp 7.Handle portion structure such as Fig. 3
It is shown, it is made of the flexible handle 2 of type and fixed handle 1, the two is hingedly fixed at inflection point；The lower end of fixed handle 1
For handheld terminal, upper end is provided with hollow official jargon, and the upper end of fixed handle 1 and the tip designs of pincers pipe are integrated, the end of pull rod 3
It protrudes into the upper end official jargon of fixed handle 1 and extends to and hingedly fixed with the upper end of flexible handle 2.According to the above design, realize
The relatively fixed clamp 6 of active clamp 7 is set to open or be closed by controlling flexible handle 2.
In addition, it is further, as shown in figure 3, the articulated shaft two sides on fixed handle 1, are respectively arranged with the first limit
