The binding buckle of the utility model includes a bracket and a plurality of slots, the slots are arranged on the bracket, and the slots are spaced in three dimensions. The surgical thread can be wound in the slot hole of the binding buckle, and the surgical thread is wound and fixed in the slot hole due to the three-dimensional distribution of the slot hole. After the surgical thread is tightened, it is difficult for the surgical thread to loosen and slip off. The binding buckle for fixing the surgical thread is very convenient to use and can be designed on the outer wall of the trocar sheath. In clinical use, the doctor uses a surgical thread with a needle to pass through the skin of the abdominal incision where the puncturer is fixed, and then wraps the surgical thread around the binding buckle to fix the puncturer firmly and prevent the puncturer from being pulled out of the abdomen when the surgical instrument is pulled out. Cut out.

Description

Lashing buckle and piercer

technical field

The utility model relates to a laparoscopic surgical instrument, in particular to a binding buckle used in laparoscopic surgery and a puncturer using the binding buckle.

Background technique

Laparoscopic surgery has been more and more widely used. In order to avoid iatrogenic infection, the amount of disposable trocar (Trocar) used in laparoscopic surgery is also increasing. On the basis of ensuring the performance, the structure is simplified , reduce cost, improve performance, this trend has become the direction of trocar improvement.

The puncture device in the prior art, in order to prevent the puncture device from being taken out of the abdominal wall and slipping off during the process of surgical instruments entering and leaving, the method adopted is to set up barbs or threads on the sheath tube to increase the penetration of the puncture device in the abdominal wall. Movement resistance to prevent the trocar from slipping out of the incision in the abdominal wall. However, due to the relatively high friction between the surgical instrument and the trocar during the entry and exit of the surgical instrument, only relying on the barbs or threads on the trocar sheath can not effectively prevent the trocar from slipping off. Therefore need to improve prior art.

Contents of the invention

The core technical proposal of the utility model relates to an easy-to-use binding buckle, which can conveniently fix the surgical thread. The utility model is achieved in that:

A binding buckle, the binding buckle 9 includes a bracket 1 and a plurality of slots 2, the slots 2 are arranged on the bracket 1, and the slots 2 are spatially distributed.

Further, the slot 2 includes a hook 21, and the hook 21 is arranged inside the slot 2 and protrudes inward.

The slot 2 is a U-shaped slot. Slots of other shapes can also be designed.

The piercer, the piercer 100 includes the binding buckle 9 according to claim 1.

The binding buckle 9 of the utility model includes a bracket 1 and a plurality of slots 2, the slots 2 are arranged on the bracket 1, and the slots 2 are spaced in three dimensions. The surgical wire 400 can be wound in the slot 2 of the binding buckle 9 , and the surgical wire 400 is wound and fixed in the slot 2 because the slot 2 adopts a three-dimensional distribution. After the surgical thread 400 is tightened, it is difficult for the surgical thread 400 to loosen and slip off. The binding buckle 9 for fixing the surgical thread 400 is very convenient to use and can be designed on the outer wall of the trocar sheath 102 . During clinical use, the doctor passes the surgical thread 400 with a needle through the skin 300 of the abdominal incision that fixes the puncture device 100, and then wraps the surgical thread 400 around the binding buckle 9, so that the puncture device can be The puncture device 100 is firmly fixed to prevent the trocar 100 from being taken out of the abdominal incision when the surgical instrument 200 is withdrawn.

Detailed ways

Embodiment 1: The binding buckle of the present utility model

Referring to Fig. 1 and Fig. 2, the binding buckle 9 of the present invention includes a bracket 1 and a plurality of slots 2, the slots 2 are arranged on the bracket 1, and the slots 2 are spatially distributed. The slot 2 is a U-shaped slot. Of course, those skilled in the art can also design the slot 2 with other shapes without departing from the protection scope of the present invention.

Because the slotted holes 2 of the binding buckle 9 of the utility model are three-dimensionally distributed in space. The slot 2 allows the surgical wire 400 to be wound and fixed. After the surgical thread 400 is tightened, it is difficult for the surgical thread 400 to loosen and slip off. The binding buckle 9 for fixing the surgical thread 400 is very convenient to use and can be arranged on the outer wall of the trocar sheath 102 . During clinical use, the doctor passes the surgical thread 400 with a needle through the skin of the abdominal incision that fixes the trocar 100, and then wraps the surgical thread 400 around the binding buckle 9, so that the trocar 100 It is firmly fixed to prevent the trocar 100 from being taken out of the abdominal incision when the surgical instrument 200 is pulled out.

Embodiment 2: The binding buckle with hook of the present utility model

Referring to FIG. 3 , the difference between this embodiment and Embodiment 1 is that in this embodiment, an inwardly protruding hook 21 is provided on the inner wall of the slot 2 , and the hook 21 is positioned on the surgical wire 400 The surgical thread 400 can be clamped after being wound around the slot 2 , preventing the surgical thread 400 from loosening and slipping off.

Embodiment 3: the puncture device of the present utility model

Referring to FIG. 4 , the piercer 100 of the present invention includes the binding buckle 9 of the present invention. The puncture device includes a puncture rod 101 and a sheath tube 102 . On both sides of the outer wall of the sheath tube 102, the binding buttons 9 of the present invention are symmetrically arranged. The binding buckle 9 includes a bracket 1 and a plurality of slots 2, the slots 2 are arranged on the bracket 1, and the slots 2 are arranged in a three-dimensional space. The slot 2 allows the surgical wire 400 to be wound and fixed. After the surgical thread 400 is tightened, since the surgical thread 400 is embedded and wound in the slot 2, many spatial corners are formed when the surgical thread 400 is wound, and these spatial corners make it difficult for the surgical thread 400 to Slack, slipping.

Referring to FIG. 5 , in clinical use, the doctor passes the surgical thread 400 with a needle through the skin 300 fixing the abdominal incision of the trocar 100 , and then wraps the surgical thread 400 around the binding buckle 9 . The trocar 100 is fixed firmly to prevent the trocar 100 from being taken out of the abdominal incision when the surgical instrument 200 is pulled out.
