Abstract
The utility model relates to a suture needle for operations on the liver. The suture needle comprises a needle body consisting of a core and a puncture sleeve. The core is inserted in the puncture sleeve which is a hollow tube and comprises a puncture portion and a handle portion. The inner diameter of the handle portion is larger than that of the puncture portion; the end of the core, out of the puncture portion, is provided with a blunt end, a retaining plate is arranged on the core inside the handle portion, a compression spring is arranged between the retaining plate and the puncture portion, and wire slots are formed, on the core, at one end of the blunt end. Without limitation of operation space, the suture needle can be applied to any narrow operation space. Due to the blunt end of the core, damage to blood vessels during suturing is avoided effectively, blooding in operations is reduced, operation quality is improved effectively, operational risk is decreased, operation difficulty of operators is lowered, and suffering of patients is relieved.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of sewing needle for operation on liver.
Background technology
The operation on liver most thorny issue is the extensive oozing of blood of surgical wound surface, and anthemorrhagic difficulty may cause hemorrhagic shock when serious, even dead.At present applicable liver suture needle has certain limitation clinically, particularly, when operative space is narrow and small, sews up comparatively difficulty, causes sometimes the liver wound surface to be torn, threat to life.
The utility model content
Goal of the invention of the present utility model is to provide a kind of sewing needle for operation on liver, this sewing needle can carry out the stitching of liver wound surface at any narrow and small operative region, and can improve the operation quality, reduces surgical risk, reduce operator's work difficulty, alleviate patient's misery.
The technical scheme in the invention for solving the above technical problem is: for the sewing needle of operation on liver, comprise needle body, needle body is comprised of inner core and puncture casing, inner core is located in puncture casing, described puncture casing is hollow tube, puncture casing comprises puncture section and handle portion, the internal diameter of handle portion is greater than the internal diameter of puncture section, the end that described inner core passes from puncture section is provided with blunt nosed, be provided with block plate on inner core in handle portion, be provided with Compress Spring between block plate and puncture section, the inner core place of a blunt nosed end is provided with wire casing.
The shape of described inner core and puncture casing is complementary, curved or linear.
The external diameter of described puncture section is 2mm-6mm, and internal diameter is 1mm-5mm, and puncture minister degree is 10mm-150mm; The external diameter of handle portion is 7mm-20mm, and internal diameter is 2mm-6mm.
The external diameter of described puncture section is 3mm, and internal diameter is 2mm, and puncture minister degree is 100mm; The external diameter of handle portion is 10mm, and internal diameter is 4mm.
The beneficial effects of the utility model: this utility model is not subject to the restriction of operative space, can be in any narrow and small operative region application, blunt nosed on its inner core also effectively avoided injured blood vessel in sewing process, reduced intraoperative hemorrhage, also effectively improved the operation quality, reduce surgical risk, reduced operator's work difficulty, alleviated patient's misery.

Fig. 1 is structural representation of the present utility model;
Reference numeral: 1, inner core, 2, puncture casing, 3, puncture section, 4, handle portion, 5, blunt nosed, 6, block plate, 7, Compress Spring, 8, wire casing.
The specific embodiment
As shown in Figure 1: for the sewing needle of operation on liver, comprise needle body, needle body is comprised of inner core 1 and puncture casing 2, inner core 1 is located in puncture casing 2, described puncture casing 2 is hollow tube, puncture casing 2 comprises puncture section 3 and handle portion 4, the internal diameter of handle portion 4 is greater than the internal diameter of puncture section 3, the end that described inner core 1 passes from puncture section 3 is provided with blunt nosed 5, be provided with block plate 6 on inner core 1 in handle portion 4, be provided with Compress Spring 7 between block plate 6 and puncture section 3, inner core 1 place of blunt nosed 5 one ends is provided with wire casing 8.
Described inner core 1 is complementary with the shape of puncture casing 2, curved or linear.
The external diameter of described puncture section 3 is 2mm-6mm, and internal diameter is 1mm-5mm, and puncture section 3 length are 10mm-150mm; The external diameter of handle portion 4 is 7mm-20mm, and internal diameter is 2mm-6mm.
Preferably, the external diameter of described puncture section 3 is 3mm, and internal diameter is 2mm, and puncture section 3 length are 100mm; The external diameter of handle portion 4 is 10mm, and internal diameter is 4mm.
Use of the present utility model, be parallel to the puncture of liver wound surface, while meeting obstructions, can change the puncture direction, press down inner core 1 while being punctured to liver wound surface opposite side, wire casing 8 is stretched out outside puncture casing 2, unclamp inner core 1 after the hook strip stitching thread, make it resilience and bring stitching thread into inner core 1, return puncture section 3 along needle track, again press down inner core 1, unclamp suture, apart from this point of puncture certain distance at repeated puncture, again take back the suture other end, tie a knot outside liver, tighten up the liver wound surface and stop blooding with abundant wound surface.
This utility model is not subject to the restriction of operative space, can be in any narrow and small operative region application, on its inner core 1 blunt nosed 5 also effectively avoided injured blood vessel in sewing process, reduced intraoperative hemorrhage, effectively improved the operation quality, reduce surgical risk, reduced operator's work difficulty, alleviated patient's misery.
