Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely is a trocar auxiliary device. BACKGROUND

[0002] In the laparoscopic assisted operation process, we often need to extend the incision from the umbilical trocar port, take the intestinal canal out

[0003] , make a simple closure with a glove, put the intestinal canal back into the abdominal cavity, reestablish the pneumoperitoneum, and then perform the colon anastomosis.

[0004]

[0005] During this process, there are many difficulties in inserting the scope, and the operation is inconvenient, and it cannot be relatively fixed in the trocar,

[0006] so it will cause deviation in operation, dirty the lens, and in severe cases, it will directly affect the field of view and operation of the main operator, and bring

[0007] not small surgical risks. SUMMARY

[0008] The utility model aims at providing a trocar auxiliary device, which can reduce the difficulty of inserting the scope and the inconvenience of operation after the transfer laparotomy.

[0009]

[0010] To achieve the above purpose, a trocar auxiliary device is provided, which comprises a mounting plate, a circular trocar inlet is arranged in the middle part of the mounting plate, and an inlet pipeline is fixedly connected in the trocar inlet.

[0011] The outer side end of the mounting plate is provided with an annular connecting groove, and the connecting groove penetrates the lower end of the mounting plate.

[0012] A rubber tightening ring is arranged in the connecting groove, and the upper end of the rubber tightening ring is fixedly connected with the top end of the sealing groove.

[0013] The trocar auxiliary device can reduce the difficulty of inserting the scope and the inconvenience of operation after the transfer laparotomy.

[0014]

[0015] According to the trocar auxiliary device, the inlet pipeline is made of silica gel, and the inner diameter of the inlet pipeline is 1.2cm.

[0016] The inner diameter of the inlet pipeline is the same as the outer diameter of the inflow pipeline of the umbilical trocar, so that the umbilical trocar can be inserted into the inlet pipeline.

[0017] ​​​​

[0018] According to the aforementioned trocar assist device, the height of the mounting plate is 1.5 cm. This avoids the inlet pipe in the mounting plate being too long or too short, which could affect the insertion efficiency or stability of the trocar's inlet pipe.

[0019] Effect.

[0020] According to the aforementioned trocar aid, the mounting plate has a diameter of 10 cm. This makes the aid larger...

[0021] Small and suitable, easy to use.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. Insert the trocar through the trocar inlet on the mounting plate and tighten it using the elasticity of the inlet pipe.

[0024] The trocar's inlet channel is enclosed, allowing the trocar to rotate 360° within the inlet pipe, reducing intermediate openings.

[0025] The difficulty of accessing the endoscope and the inconvenience of performing laparoscopic surgery again after abdominal surgery.

[0026] 2. The elasticity of the rubber tightening ring at the top of the connecting groove in the mounting plate allows the rubber tightening ring to be pulled downwards.

[0027] The length is such that it wraps around the trocar's protective ring, connecting the two and preventing the aid from moving during use.

[0028] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part from the description itself.

[0029] As will become apparent from the description, or as will be learned through practice of this utility model. Attached Figure Description
