Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an anti-slip laparoscope puncture card. Background Art

[0002] Laparoscopic puncture card (puncture device TROCAR) is a relatively advanced treatment method that can be applied to benign diseases. It can have a certain therapeutic effect on people with early tumors and other groups. Generally, it can be used to treat diseases such as extraperitoneal hernia repair, gastrointestinal perforation repair, colorectal tumor resection, and liver cyst fenestration drainage.

[0003] During the treatment process, there is little trauma, recovery is quick, and satisfactory treatment effects can be achieved. Surgical operations can usually be performed precisely on the lesion site.

[0004] The poking card usually consists of a tubular instrument with a sharp edge and a handle, which is easy to slip when inserted into the patient's body, which is not conducive to subsequent treatment operations. Therefore, we propose an anti-slip laparoscopic poking card. Utility Model Content

[0005] The utility model aims to provide an anti-skidding laparoscope puncture card, which has the effect of preventing the puncture card from slipping easily when being put into a patient's body.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an anti-slip laparoscopic puncture card, including a puncture sleeve, a connecting sleeve installed on the right side of the puncture sleeve, a connecting head threadedly connected to the connecting sleeve, and a puncture core connected to the connecting head, two mounting rings are installed on the outside of the puncture sleeve, an anti-slip positioning component is also provided on the outside of the puncture sleeve, an inflation component for inflating the anti-slip positioning component is provided on the puncture sleeve, and a connecting component for moving the anti-slip positioning component left and right is also provided on the puncture sleeve.

[0007] By adopting the above technical scheme, during puncture, the puncture cannula and the patient's peritoneum are initially positioned, and then the connector is rotated to drive the puncture core to pierce the skin tissue, and then the connector and the puncture core are taken out by reverse rotation, and a channel for laparoscopic surgical instruments to enter and exit is formed inside the puncture cannula and the connecting sleeve. During the operation, the mounting ring can be held by hand to prevent the puncture cannula from slipping. At the same time, the inflation component is used to inflate the anti-slip positioning component to increase the contact area between the puncture cannula and the patient's skin tissue, further preventing the puncture cannula from slipping. At the same time, the connecting component is used to change the position of the anti-slip positioning component on the puncture cannula, so that the distance from the anti-slip positioning component to the patient's skin can be changed according to the abdominal wall thickness of different patients, further improving the fit between the anti-slip positioning component and the patient's skin to prevent slipping.

[0008] The utility model is further configured as follows: the interior of the puncture sleeve is hollow, the right side of the inner wall thereof is open, and the left end of the puncture sleeve is an inclined surface.

[0009] By adopting the above technical solution, the setting of the inclined surface makes it easier to rotate the puncture core to puncture the skin tissue after the puncture cannula and the peritoneum are initially positioned.

[0010] The utility model is further configured as follows: the interior of the connecting sleeve is hollow and both left and right sides of the inner wall thereof are open.

[0011] By adopting the above technical solution, a passage for laparoscopic surgical instruments to enter and exit is conveniently formed inside the puncture sleeve and the connecting sleeve after the puncture core is taken out.

[0012] The utility model is further configured as follows: the anti-slip positioning assembly comprises an annular plate sleeved outside the puncture sleeve and an annular rubber ring mounted on the annular plate and sleeved outside the puncture sleeve.

[0013] By adopting the above technical solution, the annular plate provides a mounting point for the annular rubber ring on the puncture sleeve, and the annular rubber ring is inflated by using the inflation assembly to increase the contact surface between the puncture sleeve and the patient's skin tissue, thereby further preventing the puncture sleeve from slipping.

[0014] The utility model is further configured as follows: a plurality of resistance-increasing convex points distributed at equal distances are installed on the left side of the annular rubber ring.

[0015] By adopting the above technical solution, the setting of the resistance-increasing protrusions further increases the frictional resistance between the annular rubber ring and the patient's skin, making the annular rubber ring fit the patient's skin better and avoiding slipping.

[0016] The utility model is further configured as follows: the inflation component comprises a mounting frame mounted on the puncture sleeve, an air bag mounted on the mounting frame, and an air pipe passing through the mounting ring and the annular plate and connecting the air bag and the annular rubber ring.

[0017] By adopting the above technical solution, the airbag is squeezed, and the gas generated by the compression of the airbag inflates the annular rubber ring through the trachea, thereby increasing the contact area between the puncture cannula and the patient's skin tissue, thereby preventing the puncture cannula from slipping.

[0018] The utility model is further configured as follows: the air pipe is a hose and a one-way valve is installed on the pipe wall of the hose on the side close to the annular plate.

[0019] By adopting the above technical solution, the setting of the hose allows the trachea to compress or expand the annular rubber ring to continuously inflate the annular rubber ring when the annular rubber ring changes its position. The setting of the one-way valve prevents gas backflow and avoids the annular rubber ring from separating from the patient's skin.

[0020] The utility model is further configured as follows: the connecting assembly includes a connecting sleeve rod installed on the puncture sleeve, a connecting support rod movably installed inside the connecting sleeve rod and rotatably connected to the annular plate at one end, and a limiting column installed on the connecting support rod and extending at one end to the top of the connecting sleeve rod.

[0021] The utility model is further configured as follows: the connection assembly further comprises a rectangular bar hole and an arc bar hole which are opened on the connection sleeve rod and matched with the limiting column.

[0022] By adopting the above technical solution, the connecting support rod can both rotate relative to the annular plate and drive it to move left and right. When the connecting support rod drives the annular plate to move left and right, the limiting column moves in the rectangular strip hole. When the annular rubber ring is driven to move to a suitable position, the connecting support rod is rotated to make the limiting column move from the rectangular strip hole to the inside of the arc-shaped strip hole, so as to change the distance from the annular rubber ring to the patient's skin according to the abdominal wall thickness of different patients, further improve the fit between the annular rubber ring and the patient's skin, and prevent slipping.

[0023] The utility model is further configured as follows: a plurality of arc-shaped strip holes are provided and are connected to the rectangular strip holes.

[0024] By adopting the above technical solution, the arrangement of multiple arc-shaped strip holes facilitates providing multiple fixing points for the limiting column.

[0025] The beneficial effects of the utility model are as follows: during operation, the installation ring can be held by hand to prevent the puncture cannula from slipping, and at the same time, the inflation component is used to inflate the anti-skid positioning component to increase the contact surface between the puncture cannula and the patient's skin tissue, further preventing the puncture cannula from slipping. At the same time, the connection component is used to change the position of the anti-skid positioning component on the puncture cannula, which is convenient for changing the distance from the anti-skid positioning component to the patient's skin according to the abdominal wall thickness of different patients, further improving the fit between the anti-skid positioning component and the patient's skin and preventing slipping.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-3 The utility model provides an anti-skid laparoscopic puncture card, comprising a puncture sleeve 1, a connecting sleeve 2 installed on the right side of the puncture sleeve 1, a connecting head 3 threadedly connected to the connecting sleeve 2 and a puncture core 4 connected to the connecting head 3, two mounting rings 5 ​​are installed on the outer side of the puncture sleeve 1, an anti-skid positioning component is also provided on the outer side of the puncture sleeve 1, an inflation component for inflating the anti-skid positioning component is provided on the puncture sleeve 1, and a connecting component for moving the anti-skid positioning component left and right is also provided on the puncture sleeve 1.

[0033] During puncture, the puncture sleeve 1 and the patient's peritoneum are initially positioned, and then the connector 3 is rotated to allow the connector 3 to drive the puncture core 4 to pierce the skin tissue. The connector 3 and the puncture core 4 are then taken out by rotating in the opposite direction. A channel for laparoscopic surgical instruments to enter and exit is formed inside the puncture sleeve 1 and the connecting sleeve 2. During the operation, the mounting ring 5 can be held by hand to prevent the puncture sleeve 1 from slipping. At the same time, the inflation component is used to inflate the anti-slip positioning component to increase the contact area between the puncture sleeve 1 and the patient's skin tissue, further preventing the puncture sleeve 1 from slipping. At the same time, the connecting component is used to change the position of the anti-slip positioning component on the puncture sleeve 1, so that the distance from the anti-slip positioning component to the patient's skin can be changed according to the abdominal wall thickness of different patients, further improving the fit between the anti-slip positioning component and the patient's skin to prevent slipping.

[0034] The interior of the puncture sleeve 1 is hollow and the right side of its inner wall is open. The left end of the puncture sleeve 1 is an inclined surface. The setting of the inclined surface facilitates the initial positioning of the puncture sleeve 1 and the peritoneum before rotating the puncture core 4 to puncture the skin tissue.

[0035] The interior of the connecting sleeve 2 is hollow and both left and right sides of its inner wall are open, so that after the puncture core 4 is taken out, a passage for laparoscopic surgical instruments to enter and exit is formed inside the puncture sleeve 1 and the connecting sleeve 2.

[0036] The anti-slip positioning component includes an annular plate 6 which is sleeved on the outside of the puncture sleeve 1 and an annular rubber ring 7 which is installed on the annular plate 6 and sleeved on the outside of the puncture sleeve 1. The annular plate 6 provides a mounting point for the annular rubber ring 7 on the puncture sleeve 1. The annular rubber ring 7 is inflated by using an inflation component to increase the contact surface between the puncture sleeve 1 and the patient's skin tissue, thereby further preventing the puncture sleeve 1 from slipping.

[0037] A number of resistance-increasing protrusions 8 are installed on the left side of the annular rubber ring 7 and are distributed at equal distances. The setting of the resistance-increasing protrusions 8 further increases the friction resistance between the annular rubber ring 7 and the patient's skin, making the annular rubber ring 7 fit the patient's skin better and avoiding slipping.

[0038] The inflation component includes a mounting frame 9 mounted on the puncture sleeve 1, an air bag 10 mounted on the mounting frame 9, and an air tube 11 passing through the mounting ring 5 and the annular plate 6 and connecting the air bag 10 and the annular rubber ring 7. The air bag 10 is squeezed, and the gas generated by the compression of the air bag 10 inflates the annular rubber ring 7 through the air tube 11, thereby increasing the contact surface between the puncture sleeve 1 and the patient's skin tissue, thereby preventing the puncture sleeve 1 from slipping.

[0039] The trachea 11 is a hose and a one-way valve 12 is installed on the tube wall on the side close to the annular plate 6. The setting of the hose allows the trachea 11 to be compressed or expanded to continuously inflate the annular rubber ring 7 when the annular rubber ring 7 changes its position. The setting of the one-way valve 12 prevents gas backflow and avoids the annular rubber ring 7 from separating from the patient's skin.

The connecting assembly also includes a rectangular strip hole 16 and an arc strip hole 17 opened on the connecting sleeve rod 13 and adapted to the limiting column 15.

[0041] The connecting rod 14 can both rotate and move left and right relative to the annular plate 6. When the connecting rod 14 drives the annular plate 6 to move left and right, the limiting column 15 moves in the rectangular strip hole 6. When the annular rubber ring 7 is driven to move to a suitable position, the connecting rod 14 is rotated to make the limiting column 15 move from the rectangular strip hole 16 to the inside of the arc-shaped strip hole 17, so as to change the distance from the annular rubber ring 7 to the patient's skin according to the abdominal wall thickness of different patients, further improve the fit between the annular rubber ring 7 and the patient's skin, and prevent slipping.

[0042] There are multiple arc-shaped strip holes 17 connected to the rectangular strip holes 16 . The arrangement of multiple arc-shaped strip holes 17 facilitates providing multiple fixing points for the limiting column 15 .
