Description
Technical Field
The utility model relates to the technical field of medical instruments. In particular to a laparoscope small incision suture puncture device which is suitable for laparoscopic surgery.
Background
The laparoscopic surgery is mature day by day, more than 95 percent of the surgeries can be completed by skillfully utilizing the laparoscopic technique, the laparoscopic surgery is minimally invasive, the incision is about 0.5-1.5cm, but the laparoscopic incision is large and reaches about 1-1.5cm because the laparoscopic incision is difficult to be enlarged or a special surgical device is used, for example, when the teratoma is taken out, the bone components are large, the teratoma is difficult to be taken out from a small incision, the incision needs to be expanded, and the incision also needs to reach 1.5cm when the myoma rotary cutter is placed. If the incision is not sutured or the sutures are weak, there is a possibility that an abdominal incision hernia will occur, which is not uncommon in the clinic. Therefore, for laparoscopic surgery, larger incisions still require the suture of the fascia and peritoneal layers to reduce the incidence of incisional hernia. Conventional suturing for patients with low abdominal fat can be easier, but is more difficult for obese, thick abdominal fat patients, especially for troca, when the troca is not passed vertically on the abdominal wall but obliquely. Since the skin incision is far away from the fascial and peritoneal incisions, conventional suture needle sutures have a certain curvature and are difficult to penetrate fat, fascia and peritoneum due to the short vertical relative distance, and therefore, an auxiliary device capable of easily and firmly puncturing the suture incision is needed in the art.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems in the prior art and provide a laparoscopic small incision suture puncture device.
The above object of the present invention is achieved by the following technical solutions:
the utility model provides a puncture device is sewed up to little incision of peritoneoscope, including the puncture needle body, the silk thread threading lacks the groove has been seted up to one side of the syringe needle of puncture needle body, be provided with the push rod button on the puncture needle body, silk thread threading lacks groove side channel along with first mounting one end fixed connection, silk thread threading lacks the groove another a pair of side channel along with second mounting one end fixed connection, the second mounting other end is connected with the stiff end of shell fragment, the internal line chamber that is provided with of pjncture needle, be provided with wire rope in the line chamber, wire rope one end is connected with the push rod button, the wire rope other end is walked around the setting and is connected with the shell fragment at the inside fixed axle of the syringe needle of puncture needle body.
