Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, in particular to an abdominal fascia suturing and puncturing device. Background Art

[0002] With the development of medical technology, minimally invasive surgery with the advantages of less trauma, faster recovery and higher cure rate has also developed rapidly. Laparoscopic surgery, as a representative of minimally invasive surgery, involves multiple departments and multiple diseases and is widely used in the field of surgery. The abdominal puncture device is a commonly used surgical instrument in abdominal surgery, which is mainly used to establish artificial pneumoperitoneum and instrument channels in laparoscopic surgery. After surgery, the inner wall of the puncture hole is too deep to be sutured surgically. Usually, a hemostatic cotton ball is stuffed in and a postoperative patch is applied on the outside to let the wound heal. Sometimes it can cause wound infection and cannot heal for a long time, resulting in abdominal infection and formation of puncture hole hernia, which brings pain to the patient. Generally, a suture device is used to suture the wound.

[0003] When using the current stapler, the puncture device must be removed from the wound before being inserted into the stapler for suturing. The process of switching instruments is cumbersome and can easily cause risks such as uneven suturing on both sides of the wound, failure to align the fascia tissue, and wound infection, thereby prolonging the healing time of the fascia.

[0021] When in use, the medical staff inserts the puncture cone 12 into the puncture sleeve 11, punctures the abdominal cavity through the side wall, then pulls out the puncture cone 12, extends the surgical instrument through the puncture sleeve 11 into the abdominal cavity for surgical treatment, pulls out the surgical instrument after the operation is completed, and inserts the stapler 2 into the puncture sleeve 11 (at this time, the No. 1 swinging member 24 is in a vertical state, the No. 2 swinging member 25 is located below the No. 1 swinging member 24, and the No. 1 swinging member 24 and the No. 2 swinging member 25 are located within the cylindrical surface formed by the inner wall of the connecting tube 21, which facilitates the stapler 2 to enter the puncture sleeve 11), so that the No. 1 swinging member 24 is located outside the opening at the lower end of the puncture sleeve 11, and then pulls the No. 1 connecting member 22 upward to move the No. 1 connecting member 22 to the outside of the connecting tube 21. The No. 1 connecting piece 22 drives the fixed shaft 23 to move upward, the fixed shaft 23 drives the No. 2 swinging piece 25 to swing, and the No. 2 swinging piece 25 drives the No. 1 swinging piece 24 to swing until the No. 1 swinging piece 24 is perpendicular to the axis of the connecting tube 21. When the No. 1 connecting piece 22 is pulled, the damper 4 keeps the suture 26 in a tensioned state, and moves the two ends of the suture 26 following the swing of the No. 1 swinging piece 24. Then, the puncture sleeve 11 is pulled upward to drive the connecting tube 21, the No. 1 swinging piece 24, etc. to move upward, so that the upper surface of the No. 1 swinging piece 24 contacts the inner wall of the abdominal side wall, and then the puncture hook 3 passes through the No. 1 threading hole 111, the No. 3 threading hole 211, the No. 4 threading hole 212, and the No. 2 threading hole 112 to penetrate into the puncture wound. The puncture hook 3 continues to penetrate the side wall until the opening of the hook groove 31 moves to the bottom of the suture 26, and then the puncture hook 3 is pulled outward, so that the lower end of the hook groove 31 contacts the suture 26, and the puncture hook 3 continues to be pulled outward. At this time, the damper 4 fixes the end of the suture 26 that is not hooked by the hook groove 31. When the puncture hook 3 is pulled outward, it drives the suture 26 to move, so that the suture 26 passes through the puncture wound side wall, No. 2 threading hole 112, No. 4 threading hole 212, No. 3 threading hole 211 and No. 1 threading hole 111 to the outside of the abdominal cavity side wall, and then the other end of the suture 26 is hooked out in the same way (in this process, the end of the suture 26 that has been hooked out remains stationary), and then Push the No. 1 connecting piece 22 downward to move the fixed shaft 23 downward, drive the No. 2 swinging piece 25 to swing, and drive the No. 1 swinging piece 24 to swing, until the No. 1 swinging piece 24 and the No. 2 swinging piece 25 swing into the cylindrical surface formed by the inner wall of the connecting tube 21, and then pull out the puncture sleeve 11, the connecting tube 21, etc., so that the two ends of the suture 26 are located on the outside of the puncture wound, and the middle part of the suture 26 remains in the abdominal cavity and passes through the side walls on both sides of the puncture wound. The wound is sutured according to the conventional method to complete the fascia suturing work; the suture puncture device can solve the problem of frequent replacement of instruments during surgery, ensure uniform suture of the wound, keep the fascia tissue aligned, reduce the risk of wound infection, and has a simple structure, easy to use, safe and reliable.

[0022] Rotating members 27 are provided at intervals on the No. 1 swinging member 24; the rotating member 27 is rotationally connected to the No. 1 swinging member 24; the two rotating members 27 on the same No. 1 swinging member 24 are connected by a connecting belt 28; the connecting belt 28 is sleeved on the two rotating members 27; the connecting belt 28 is in a tensioned state; a No. 2 connecting member 29 is inserted into the connecting tube 21; a driving part 291 is provided at the lower end of the No. 2 connecting member 29.

[0023] When the lower opening of the puncture wound opens to both sides, the distance between the suture 26 and the edge of the lower opening of the puncture wound is too small. When the puncture wound is sutured, the suture 26 is easy to cut the lower opening, and effective suturing cannot be performed. By setting a connecting belt 28, the connecting belt 28 contacts the inner wall of the abdominal side wall, and the No. 2 connecting piece 29 is moved downward, so that the driving part 291 contacts the outer wall of the two connecting belts 28 close to each other at one end, driving the connecting belt 28 to move, and the connecting belt 28 drives the edge of the lower opening of the puncture wound to move, so that the edge of the lower opening of the puncture wound contacts the puncture sleeve 11, ensuring the distance between the suture 26 and the edge of the lower opening of the puncture wound, preventing the suture 26 from cutting the lower opening of the puncture wound, and performing effective suturing.

[0024] The damper 4 includes a fixing part 41, a friction part 42 and a No. 3 connecting part 43; the upper end of the connecting tube 21 is fixedly connected to the fixing part 41; both ends of the fixing part 41 are fixedly connected to the friction part 42; a No. 4 threading groove is provided in the friction part 42; the two ends of the suture thread 26 pass through the two No. 4 threading grooves respectively; a No. 3 connecting part 43 is provided above the friction part 42; the No. 3 connecting part 43 is threadedly connected to the fixing part 41.

[0025] The friction member 42 provides friction for the suture 26, so that the suture 26 remains in a tensioned state and the two ends of the suture 26 move following the swing of the No. 1 swing member 24; when one end of the suture 26 needs to be fixed, the No. 3 connecting member 43 above that end of the suture 26 is rotated so that the No. 3 connecting member 43 is squeezed onto the friction member 42, causing the friction member 42 to deform, thereby increasing the friction force on the end of the suture 26 and fixing the end of the suture 26.

[0026] The outer wall of the connecting belt 28 is provided with protrusion structures 281 at even intervals.

[0027] The raised structure 281 increases the friction between the connecting belt 28 and the driving part 291, thereby improving the reliability of the movement of the connecting belt 28; the raised structure 281 increases the friction on the side wall of the abdominal cavity, increases the probability of the lower end opening of the puncture wound moving toward the outer wall of the puncture sleeve 11, and improves the reliability of the suture puncture device.

[0028] A No. 2 connecting portion 213 is provided at the upper end of the connecting pipe 21; a No. 2 plane structure 2131 is provided on one side of the No. 2 connecting portion 213; a No. 2 avoidance groove 2132 is provided on the No. 2 plane structure 2131; a No. 4 connecting piece 214 is provided in the No. 2 avoidance groove 2132; one end of the No. 4 connecting piece 214 is threadedly connected to the No. 1 connecting piece 22; and a No. 4 limiting portion 2141 is provided at the other end of the No. 4 connecting piece 214.

[0029] When the No. 1 connecting member 22 needs to move, the No. 4 connecting member 214 is rotated to disengage the No. 4 limiting portion 2141 from the No. 2 planar structure 2131, so that the No. 1 connecting member 22 forms a sliding connection with the connecting tube 21, driving the No. 1 connecting member 22 to move; after the No. 1 swinging member 24 is perpendicular to the axis of the connecting tube 21, the No. 4 connecting member 214 is rotated in the opposite direction to make the No. 4 limiting portion 2141 contact the No. 2 planar structure 2131, thereby fixing the No. 1 connecting member 22 and the connecting tube 21, and preventing the No. 1 connecting member 22 from being re-engaged. The swing member 24 moves downward under the action of the force, preventing the No. 1 swing member 24 from swinging downward and preventing the No. 1 swing member 24 from detaching from the side wall of the abdominal cavity; the No. 2 avoidance groove 2132 limits the movement range of the No. 4 connecting member 214. When the No. 4 connecting member 214 is located at the uppermost end of the No. 2 avoidance groove 2132, the No. 1 swing member 24 is perpendicular to the axis of the connecting tube 21. When the No. 4 connecting member 214 is located at the lowermost end of the No. 2 avoidance groove 2132, the No. 1 swing member 24 and the No. 2 swing member 25 are within the cylindrical surface formed by the inner wall of the connecting tube 21.

[0031] The third rectangular portion 32 is inserted into the third rectangular groove 2151, and the side wall of the third rectangular groove 2151 guides the side wall of the third rectangular portion 32, and guides the puncture hook 3, so as to prevent the puncture hook 3 from deviating from the suture 26 and failing to hook the suture 26, thereby improving the reliability of the puncture hook 3; when the puncture hook 3 is inserted, the lower end surface of the hand-held portion of the puncture hook 3 (the upper end of the third rectangular portion 32 is provided with a hand-held portion) abuts against the end surface of the third limiting portion 216, and at this time, the opening of the hook groove 31 is just below the suture 26, so as to limit the insertion depth of the puncture suture 2, prevent the puncture suture 2 from being inserted too much and puncturing the abdominal organs, and prevent the puncture suture 2 from being inserted insufficiently and failing to hook the suture 26, thereby improving the reliability of the puncture hook 3.

[0032] A fixing structure 221 is provided on one side of the lower end of the No. 1 connecting member 22 close to the No. 3 connecting structure 243; one end of the fixing shaft 23 is fixedly connected to the fixing structure 221; the end face of the other end of the fixing shaft 23 is flush with the end face of the No. 2 swinging member 25; the No. 1 swinging member 24 is rotatably connected to the connecting tube 21 through the No. 1 connecting shaft 222; the suture line 26 passes around the bottom of the two No. 1 connecting shafts 222.

[0033] When the puncture sleeve 11, the connecting tube 21, etc. are pulled out, the end surface of the fixed shaft 23 is flush with the end surface of the second swinging member 25, avoiding the suture line 26 so that the middle part of the suture line 26 remains in the abdominal cavity.

[0034] A No. 1 connection part 113 is provided at the upper end of the puncture sleeve 11; a No. 1 limiting protrusion 1131 is symmetrically provided on the upper end surface of the No. 1 connection part 113; a No. 1 limiting groove 1132 is provided on the inner wall of the upper end of the puncture sleeve 11; a No. 2 limiting structure 217 is provided on the outer wall of the upper end of the connecting tube 21; a No. 2 limiting groove is symmetrically provided on the lower end surface of the No. 2 connection part 213; a handle 121 is provided at the upper end of the puncture cone 12; a No. 3 limiting groove is symmetrically provided on the lower end surface of the handle 121; a No. 3 limiting structure 122 is provided on the outer wall of the upper end of the puncture cone 12.
