Description

Technical Field

[0001] This invention belongs to the field of purse-string pliers technology, specifically a flexible purse-string cutting integrated pliers. Background Technology

[0002] Purse-string forceps, also known as purse-string staplers, are mainly used to provide temporary purse-string closure during intestinal, colonic, rectal, and esophageal surgeries.

[0003] Patent CN215079311 U discloses a purse-grip pliers, including a handle, a gripper sleeve, and a connecting rod. The connecting rod has a clamp at its end. The left and right clamps each have corresponding left and right clamp teeth, and each left and right clamp tooth has a corresponding locking part. Each left and right clamp tooth has a through-hole for threading. This patent, by setting up a clamp consisting of corresponding left and right clamps, and with the threading groove on the left and right clamp teeth, allows the left and right clamp teeth to engage and clamp together during clamping. The threading groove on both forms a threading tightening hole, enabling it to be used for... The purse-string suture is passed through during surgery to facilitate purse-string suturing. Patent CN209437307U discloses a clamping device for a laparoscopic purse-string suture device, including a power generating device in the handle part, a power transmission device in the transmission rod part, and a power conversion clamping device in the clamping head part. This patent allows operation in the confined space of minimally invasive and open surgeries, reducing surgical risks. The minimally invasive approach is beneficial to patient recovery. The clamping head can rotate to adapt to operation in different positions and is applicable to various medical settings.

[0004] To facilitate the use of purse-string forceps for closure of the intestines and esophagus by medical staff, the forceps head is usually perpendicular to the forceps bar. This results in the forceps head occupying a large amount of space. When purse-string forceps need to be used inside a patient, a large enough incision needs to be made in the patient's body to allow the forceps to pass through. The large space occupied by the forceps results in a large incision, which can cause damage to the patient and is not conducive to postoperative recovery. In addition, when it is necessary to remove excess tissue after using purse-string forceps to close the tissue, the tissue needs to be cut again, which increases the surgical procedure and the surgical risk.

[0034] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0035] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0036] Reference Figures 1-12 The flexible purse-cutting pliers of the present invention include a pliers body 1, which is formed by a pair of pliers 11 hinged together. By moving the head end of the pliers 11, the ends of the two pliers 11 can be brought closer or further apart.

[0037] In this invention, the end of the forceps body 1 is hinged with a movable forceps head 2. The movable forceps head 2 includes a bottom forceps head 21 hinged to the end of the bottom forceps bar 11 and a top forceps head 22 hinged to the end of the top forceps bar 11. The top surface of the bottom forceps head 21 is fixed with several pairs of bottom protrusions 211, and the bottom surface of the top forceps head 22 is fixed with several pairs of top protrusions 221. When the ends of the forceps bar 11 approach each other, the bottom protrusions 211 abut against the top protrusions 221, thereby clamping the patient's tissue in the movable forceps head 2.

[0038] Specifically, a bottom insert 212 is provided between several bottom protrusions 211, and a top insert 222 is provided between several top protrusions 221. A pin 2221 is provided at the bottom end of the top insert 222, which can penetrate the bottom insert 212. Several hanging holes 2121 are provided on the bottom insert 212. The hanging holes 2121 are through holes, and the inner diameter of the opening of the hanging hole 2121 is smaller than the diameter of the hole. The positions of the pin 2221 and the hanging holes 2121 are... Correspondingly, the end of the insertion needle 2221 is provided with a hook connector 2222. When the end of the insertion needle 2221 is inserted into the hook hole 2121, it can be hooked in the hook hole 2121. When the patient's tissue is clamped using the movable forceps head 2, the insertion needle 2221 can penetrate and approach the clamped tissue. When the end of the insertion needle 2221 passes through and is hooked in the hook hole 2121, the bottom insert 212 and the top insert 222 will clamp on both sides of the patient's tissue, thereby achieving the purpose of closing the wound.

[0039] Furthermore, each of the two clamping rods 11 has a hinge joint 111 at its end. Damping rubber plates 112 are tightly bonded to the two adjacent end faces of the two hinge joints 111. The first end of the bottom clamping head 21 has a first hinge groove 213, and the first end of the top clamping head 22 has a second hinge groove 223. The two hinge joints 111 extend into the first hinge groove 213 and the second hinge groove 223 respectively and are rotatably connected to the bottom clamping head 21 and the top clamping head 22 respectively, so that the movable clamping head 2 can rotate at the end of the clamping body 1, thereby moving the movable clamping head 2 to a vertical or flush position on the clamping body 1. At the same time, under the action of the damping rubber plate 112, the movement of the bottom clamping head 21 and the top clamping head 22 will be subject to a certain resistance, so that the movable clamping head 2 can be suspended at the current position after being rotated by the damping plate and will not move randomly. When the movable forceps head 2 rotates at the end of the forceps body 1 and remains flush with the forceps body 1, the forceps body 1 can drive the movable forceps head 2 through a narrow incision on the patient's body and into the patient's body, such as a cannula for laparoscopic insertion, thereby reducing the size of the incision on the patient's body and thus reducing the patient's pain. After the movable forceps head 2 is inserted into the patient's body, the movable forceps head 2 can be rotated to a perpendicular position to the forceps body 1 by turning the head of the movable forceps head 2. At this time, the movable forceps head 2 can be used to clamp the patient's tissue.

[0040] Furthermore, since both the bottom jaw 21 and the top jaw 22 can rotate at the end of the jaw body 1, in order to prevent the bottom jaw 21 and the top jaw 22 from becoming misaligned and unable to close, such as... Figure 4 , Figure 5 and Figure 7 As shown, a positioning block 214 is fixed at the top surface of the bottom jaw 21, and a positioning groove 2141 is provided on the positioning block 214. An insert plate 224 is fixed at the bottom surface of the top jaw 22. When the bottom jaw 21 and the top jaw 22 are closed together, the insert plate 224 is inserted into the positioning groove 2141, so that the bottom jaw 21 and the top jaw 22 can be restricted to a flush state under the insertion of the positioning block 214 and the insert plate 224, thereby preventing the bottom jaw 21 and the top jaw 22 from being misaligned.

[0041] In the above scheme, in order to better insert the pin 2221 into the hanging hole 2121, a pressing mechanism 3 is provided on the side of the clamp body 1. The pressing mechanism 3 includes a lever 31 rotatably connected to the clamp bar 11 and a pressing plate 32 hinged to the end of the lever 31.

[0042] Specifically, a baffle 113 is provided on the outer surface of the head of the clamp 11, which is hinged to the top clamp head 22. The head of the lever 31 rests against the baffle 113, which acts as a stop to limit the range of motion of the head of the lever 31 and prevent it from rotating excessively. A lever plate 312 is provided on the outer surface of the head of the lever 31, so that medical personnel can rotate the lever 31 around the clamp body 1 by moving the lever plate 312, thereby causing the lever 31 to move the abutment plate 32.

[0043] Furthermore, the end of the lever 31 is provided with a protruding rod 311, and a protruding post 313 is fixed on the side surface of the protruding rod 311. A rotating seat 323 is rotatably connected to the top surface of the head end of the abutment plate 32. A through-shaped movable groove 3231 is opened on the side surface of the rotating seat 323. The protruding post 313 passes through the movable groove 3231. Under the action of the rotating seat 323, the abutment plate 32 can rotate around the end of the lever 31, so that the abutment plate 32 can rotate synchronously with the rotation of the movable pliers head 2, so that the abutment plate 32 always follows the movement of the movable pliers head 2.

[0044] In addition, the bottom surface of the abutment plate 32 is fixed with several push pins 321, and the top surface of the top clamp head 22 is provided with several through holes 225. The number of through holes 225 is equal to the number of push pins 321 and their positions correspond one-to-one. The end of the push pin 321 extends into the through hole 225, so that the push pin 321 is inserted into the top clamp head 22. When the lever 31 is turned to press the abutment plate 32 downward, the abutment plate 32 will push the push pin 321 downward and press the push pin 321 downward to press the top insert 222. At this time, the top insert 222 can drive the pin 2221 to be inserted into the hanging hole 2121.

[0045] It is worth noting that a cutting blade 322 is fixed at the bottom edge of the abutment plate 32, and a through groove 226 is provided at the top edge of the top jaw 22. The cutting blade 322 passes through the through groove 226, so that the cutting blade 322 penetrates the top jaw 22. When the bottom jaw 21 and the top jaw 22 are closed, the end of the lever 31 can be pushed upward to press down the abutment plate 32 and cause the abutment plate 32 to drive the cutting blade 322 to abut against the top surface of the bottom jaw 21. Thus, the patient tissue held by the movable jaw 2 can be cut under the pressure of the cutting blade 322, thereby achieving the purpose of cutting off excess tissue.

[0046] The working principle of the flexible purse-string cutting pliers of the present invention is as follows:

[0047] First, by manipulating the movable forceps head 2 until it is flush with the forceps body 1, the movable forceps head 2 can be inserted into the patient's body through a narrow incision, avoiding the need for a large incision. Then, after the movable forceps head 2 is inserted into the patient's body, other instruments are used to manipulate it until it expands and is perpendicular to the forceps body 1. The opening and closing of the forceps body 1 is then controlled to allow the movable forceps head 2 to clamp the patient's tissue. Finally, after the movable forceps head 2 has clamped the patient's tissue, the lever 312 is activated by manipulating the lever 3. 1. Press down on the abutment plate 32. At this time, the abutment plate 32 pushes the top insert 222 downward through the push post 321, so that the needle 2221 penetrates the tissue and is inserted and hooked into the hanging hole 2121, so as to close the patient's tissue. At this time, as the push plate 312 is pressed, the abutment plate 32 can drive the cutting blade 322 to move towards the patient's tissue. When the cutting blade 322 touches the bottom forceps head 21, the patient's excess tissue is removed by the cutting blade 322, thus completing the removal of excess tissue and closure of the wound in one go, reducing the surgical procedure.

[0048] The foregoing description of specific exemplary embodiments of the invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the invention, as well as various different choices and variations.
