Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates 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 surgical operations. 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. The inner wall of the puncture hole after surgery 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 allow the wound to heal. Sometimes it will cause wound infection and cannot heal for a long time, resulting in abdominal infection and the 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 lead to uneven suturing on both sides of the wound, fascia tissue cannot be aligned, and wound infection, which prolongs the healing time of the fascia.

The puncture sleeve is pulled upward so that the upper surface of the No. 1 swinging member contacts the inner wall of the abdominal side wall. Then, the puncture thread hook is inserted into the side wall of the puncture wound until the opening of the thread hook groove moves below the suture line. The puncture thread hook is pulled outward so that the lower end of the thread hook groove contacts the suture line. The puncture thread hook is continued to be pulled outward so that the suture line is hooked out to the outside of the abdominal side wall. Then, the other end of the suture line is hooked out in the same way. Then push the No. 1 connecting piece downward until the No. 1 swinging piece and the No. 2 swinging piece swing into the cylindrical surface formed by the inner wall of the connecting tube, pull out the puncture cannula, connecting tube, etc., so that the two ends of the suture are located on the outside of the puncture wound, the middle part of the suture 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; this suturing and 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.

[0020] 2. In the present invention, the second connecting piece is moved downward, so that the driving part contacts the outer wall of the two connecting belts close to one end, driving the connecting belt to move, and the connecting belt 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, ensuring the distance between the suture line and the edge of the lower opening of the puncture wound, preventing the suture line from cutting the lower opening of the puncture wound, and performing effective suturing.

[0021] 3. The friction member in the present invention provides friction for the suture, so that the suture remains in a tensioned state and the two ends of the suture move following the swing of the No. 1 swing member; when one end of the suture needs to be fixed, the No. 3 connecting member above the end of the suture is rotated so that the No. 3 connecting member is squeezed onto the friction member, causing the friction member to deform, thereby increasing the friction force on the end of the suture and fixing the end of the suture.

[0022] 4. The raised structure in the present invention increases the friction between the connecting belt and the driving part, thereby improving the reliability of the movement of the connecting belt; the raised structure increases the friction on the side wall of the abdominal cavity, thereby increasing the probability of the lower end opening of the puncture wound moving toward the outer wall of the puncture cannula, thereby improving the reliability of the suture puncture device.

[0047] A first columnar structure 241 and a second columnar structure 242 are symmetrically provided on both sides of the first swing member 24 away from one end of the connecting tube 21; a first threading groove 2411 is provided on the first columnar structure 241; a first avoidance groove 2412 is provided on the first columnar structure 241; a second threading groove 2421 is provided on the second columnar structure 242; a third connecting structure 243 is provided on one side of the first swing member 24; the third connecting structure 243 and the second columnar structure 242 are arranged on the same side; a third threading groove 2431 is provided on the third connecting structure 243;

[0048] One end of the suture thread 26 passes through the No. 1 threading groove 2411, the No. 2 threading groove 2421, and the No. 3 threading groove 2431 on one side of the axis of the connecting tube 21 in sequence; the other end of the suture thread 26 passes through the No. 1 threading groove 2411, the No. 2 threading groove 2421, and the No. 3 threading groove 2431 on the other side of the axis of the connecting tube 21 in sequence; the upper end of the connecting tube 21 is connected to the damper 4; both ends of the suture thread 26 are arranged in the damper 4; the damper 4 is used to keep the suture thread 26 taut;

[0049] The side wall of the puncture sleeve 11 is symmetrically provided with a No. 1 threading hole 111; the side wall of the puncture sleeve 11 is symmetrically provided with a No. 2 threading hole 112; the side wall of the connecting tube 21 is symmetrically provided with a No. 3 threading hole 211; the side wall of the connecting tube 21 is symmetrically provided with a No. 4 threading hole 212;

[0050] A thread hooking groove 31 is provided at the end of the puncture thread hooking device 3 .

[0051] During 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 out of the connecting tube 21. The No. 1 connecting member 22 drives the fixed shaft 23 to move upward, the fixed shaft 23 drives the No. 2 swinging member 25 to swing, and the No. 2 swinging member 25 drives the No. 1 swinging member 24 to swing until the No. 1 swinging member 24 is perpendicular to the axis of the connecting tube 21. When the No. 1 connecting member 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 member 24. Then, the puncture sleeve 11 is pulled upward, driving the connecting tube 21, the No. 1 swinging member 24, etc. to move upward, so that the upper surface of the No. 1 swinging member 24 contacts the inner wall of the abdominal cavity 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 pierce 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 out, so that the lower end of the hook groove 31 contacts the suture 26, and the puncture hook 3 is continued to be pulled out. 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 out, the suture 26 is driven 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 (the end of the suture 26 that has been hooked out remains stationary during this process), 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 thread 26 are located on the outside of the puncture wound, the middle part of the suture thread 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; this suturing and puncture device can solve the problem of frequent replacement of instruments during surgery, ensure that the wound is sutured evenly, the fascia tissue remains aligned, and the risk of wound infection is reduced. It has a simple structure, is easy to use, and is safe and reliable.

[0052] Rotating members 27 are provided at intervals on the No. 1 swinging member 24; the rotating member 27 is rotatably 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.

[0053] 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 the connecting belt 28, the connecting belt 28 is in contact with the inner wall of the abdominal side wall, and the No. 2 connecting piece 29 is moved downward, so that the driving part 291 is in contact with the outer wall of the two connecting belts 28 close to 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 is in contact with 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.

[0054] 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 line 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.

[0055] 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 the 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.

[0056] Protrusion structures 281 are evenly spaced on the outer wall of the connecting belt 28 .

[0057] 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, thereby increasing the probability of the lower end opening of the puncture wound moving toward the outer wall of the puncture sleeve 11, thereby improving the reliability of the suture puncture device.

[0058] A No. 2 connecting portion 213 is provided at the upper end of the connecting pipe 21; a No. 2 planar 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 planar 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.

[0059] 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 pipe 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 pipe 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, fixing the No. 1 connecting member 22 and the connecting pipe 21, and preventing the No. 1 connecting member 22 from being re-engaged. The fourth connecting member 214 moves downward under the action of the force, preventing the No. 1 swinging member 24 from swinging downward and preventing the No. 1 swinging 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 swinging 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 swinging member 24 and the No. 2 swinging member 25 are within the cylindrical surface formed by the inner wall of the connecting tube 21.

[0060] The upper end of the connecting tube 21 is symmetrically provided with a third connecting portion 215 ; the end of the third connecting portion 215 is provided with a third limiting portion 216 ; the third connecting portion 215 is provided with a third rectangular groove 2151 ; the upper end of the puncture hook 3 is provided with a third rectangular portion 32 .

[0061] The third rectangular portion 32 is inserted into the third rectangular groove 2151, and the side walls of the third rectangular groove 2151 guide the side walls of the third rectangular portion 32, thereby guiding the puncture thread hook 3, preventing the puncture thread hook 3 from deviating from the suture 26 and failing to hook the suture 26, thereby improving the reliability of the puncture thread hook 3. When the puncture thread hook 3 is inserted, the lower end surface of the handheld portion of the puncture thread hook 3 (the upper end of the third rectangular portion 32 is provided with a handheld portion) of the puncture thread hook 3 abuts against the end surface of the third limiting portion 216. At this time, the opening of the thread hook groove 31 is just below the suture 26, thereby limiting the insertion depth of the puncture suture device 2, preventing the puncture suture device 2 from puncturing too much and injuring the abdominal organs, and preventing the puncture suture device 2 from failing to penetrate into place and failing to hook the suture 26, thereby improving the reliability of the puncture thread hook 3.

[0062] A fixing structure 221 is provided on the side of the lower end of the No. 1 connecting member 22 close to the No. 3 connecting structure 243; one end of the fixed shaft 23 is fixedly connected to the fixing structure 221; the end face of the other end of the fixed 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.
