Description

Technical Field

[0001] This utility model relates to the field of exposure forceps technology, and in particular to a multifunctional needle-type exposure forceps for bariatric and metabolic surgery. Background Technology

[0002] Needle-type exposure forceps are a special surgical instrument mainly used to fix and pull apart human tissues during surgery to provide a clear surgical field. This type of exposure forceps is usually used for smaller incisions or specific surgical sites. In weight loss and metabolic surgery, the exposure forceps are an important surgical instrument, mainly used to maintain a clear surgical field during surgery and facilitate surgical operations.

[0003] Currently, surgical exposure forceps typically come with only two spreading plates, or clamping plates. These spreading plates are mainly used to pull human tissue apart to the sides. However, this design has some obvious limitations: due to the small number and area of ​​the spreading plates, the exposure forceps can only pull human tissue apart to the sides, and cannot open up the human tissue while clamping, thus failing to provide a larger surgical field. This greatly limits the surgeon's operation, and the surgeon may need to frequently adjust the position of the exposure forceps, increasing the operation time and complexity. The small area of ​​the spreading plates means that they have less contact area with human tissue, which may lead to excessive local pressure and increase the risk of human tissue damage.

[0004] Therefore, it is necessary to design a multifunctional needle-type exposure forceps for bariatric and metabolic surgery. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a multifunctional needle-type exposure forceps for bariatric and metabolic surgery.

[0006] The technical solution of this utility model is as follows: a multifunctional needle-type exposure forceps for weight loss and metabolic surgery, comprising a piston assembly, a piston rod, a needle tube, an exposure forceps, a clamping plate, a connecting rod, a swing plate, a spreading plate, a pushing sleeve, and contact blocks. The piston rod is slidably connected inside the piston assembly, and a needle tube is disposed on the piston assembly. An exposure forceps is slidably connected to the lower inner side of the needle tube. The exposure forceps is connected to the piston rod. A clamping plate is connected to the lower part of the exposure forceps. The clamping plate is initially in a tightened state. Four connecting rods are symmetrically connected to the lower outer wall of the needle tube. A swing plate is rotatably connected to each connecting rod. A spreading plate is rotatably connected between the upper and lower swing plates, and the lower swing plate is located inside the spreading plate. A pushing sleeve is fixedly connected to the exposure forceps. Contact blocks are connected to the upper swing plate. The contact blocks pass through the needle tube and are slidably connected to the needle tube. The contact blocks are all located below the pushing sleeve.

[0007] Furthermore, it is particularly preferred that the piston assembly is threadedly connected to the needle tube, and that the piston rod is extendable.

[0008] Furthermore, it is particularly preferred that a torsion spring is also included, with a torsion spring connecting both the connecting rod and the swing plate.

[0009] In addition, it is particularly preferred that the expansion plates also include anti-stick pads, with anti-stick pads fixedly connected to the opposite sides of each other.

[0010] In addition, it is particularly preferred that the pad also includes rubber balls, with multiple rubber balls attached to each anti-stick pad.

[0011] Furthermore, it is particularly preferred that a protective ring is also included, with the protective ring connected to the end of the needle tube away from the piston assembly.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This utility model, by installing a swing plate, a spreading plate, and a contact block, and because this exposure forceps is equipped with four extension plates, allows the exposure forceps to spread out a larger area of ​​human tissue, effectively expanding the surgical operation area and facilitating the doctor's surgical operation. Furthermore, the increased area of ​​the spreading plate indicates that the contact area between the exposure forceps and human tissue has also increased, thus reducing the likelihood of excessive local pressure on human tissue that could lead to tissue damage.

[0023] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0024] Example: A multifunctional needle-type exposure forceps for bariatric and metabolic surgery, such as Figures 1-6 As shown, the assembly includes a piston assembly 1, a piston rod 111, a needle tube 101, an exposure clamp 2, a connecting rod 3, a swing plate 4, a spreading plate 5, a push sleeve 6, and a contact block 7. The piston rod 111 is internally connected to the piston assembly 1 via a sliding connection, and the piston rod 111 is extendable. The needle tube 101 is threaded onto the piston assembly 1. The exposure clamp 2 is slidably connected to the lower inner side of the needle tube 101 via a sliding connection. The exposure clamp 2 is fixedly connected to the piston rod 111. Clamping plates 21 are symmetrically connected to the lower left and right sides of the exposure clamp 2. The clamping plates 21 are initially in a tightened state. Four connecting rods 3 are symmetrically connected vertically to the lower outer wall of the needle tube 101. A swing plate 4 is rotatably connected to each connecting rod 3. A spreading plate 5 is rotatably connected between the upper and lower swing plates 4. Plate 4 is located inside the spreading plate 5. A push sleeve 6 is fixedly connected to the exposure forceps 2. Contact blocks 7 are connected to the upper swing plates 4. The contact blocks 7 pass through the needle tube 101 and are slidably connected to the needle tube 101. The contact blocks 7 are all located below the push sleeve 6. Pushing the piston rod 111, the piston rod 111 moves the push sleeve 6 down. When the push sleeve 6 contacts the contact block 7 and continues to move down, the contact block 7 will tilt upward, causing the upper swing plate 4 to rotate upward. At this time, the spreading plate 5 will expand outward as the swing plate 4 rotates upward. During this process, the lower swing plate 4 will rotate as the spreading plate 5 expands. Since the exposure forceps 2 is equipped with four expansion plates, the exposure forceps 2 can spread human tissue over a larger area, effectively expanding the area of ​​the surgical operation area.

[0025] like Figures 6-8As shown, it also includes a torsion spring 8, an anti-adhesion pad 9, a rubber ball 10, and a protective ring 11. A torsion spring 8 is connected between the connecting rod 3 and the swing plate 4. The torsion spring 8 will move the swing plate 4 down to reset, thereby improving the reset efficiency of the exposure forceps 2. An anti-adhesion pad 9 is fixedly connected to the side of the spreading plate 5 that is far away from each other. Multiple rubber balls 10 are connected to the anti-adhesion pad 9. A protective ring 11 is connected to the end of the needle tube 101 that is far away from the piston assembly 1. The anti-adhesion pad 9 on the extension plate can effectively prevent human tissue from sticking to the extension plate, so that human tissue will not be involved when adjusting or withdrawing the exposure forceps 2. The rubber ball 10 can reduce the contact between human tissue and the anti-adhesion pad 9, further preventing the exposure forceps 2 from pulling human tissue.

[0026] Before using the exposure forceps 2, it needs to be sterilized. When using the exposure forceps 2 to open up human tissue, first, align the lower end of the needle tube 101 with the human tissue, then push the piston rod 111 inside the piston assembly 1. The piston rod 111 will move the exposure forceps 2 downwards inside the needle tube 101, and the pushing sleeve 6 will also move downwards. When the pushing sleeve 6 contacts the contact block 7 and continues to move downwards, the contact block 7 will tilt upwards, causing the upper swing plate 4 to rotate upwards, and the torsion spring 8 to tighten. At this time, the opening plate 5 will expand outwards as the swing plate 4 rotates upwards. During this process, the lower swing plate 4 will rotate as the opening plate 5 expands. Because the exposure forceps 2 is equipped with four expansion plates, thus... The exposed forceps 2 can expand the area of ​​human tissue, effectively increasing the surgical operating area and facilitating surgical operations. The increased area of ​​the expansion plate 5 indicates a larger contact area between the exposed forceps 2 and the human tissue, thus reducing the risk of localized pressure damage. The protective ring 11 on the push sleeve 6 reduces damage to surrounding human tissue, and the anti-adhesion pad 9 on the expansion plate effectively prevents human tissue from adhering to the expansion plate, ensuring that the exposed forceps 2 will not be pulled during adjustment or withdrawal. The rubber ball 10 further reduces contact between human tissue and the anti-adhesion pad 9, further preventing the exposed forceps 2 from pulling on the human tissue. During the downward movement of the exposure forceps 2, the lower end of the exposure forceps 2 will extend beyond the lower end of the syringe 101. The clamping plate 21 is initially in a tightened state. As the exposure forceps 2 gradually extends beyond the lower end of the syringe 101, the clamping plate 21 will gradually expand outward, increasing the distance between the clamping plates 21. At this time, the human tissue or internal organs to be clamped are located between the clamping plates 21. Then, the piston rod 111 is pulled upward, causing the exposure forceps 2 to move upward and tighten the clamping plates 21, clamping and fixing the human tissue or internal organs. This effectively prevents the movement of human tissue or internal organs during surgery, thus facilitating the surgeon's operation and reducing surgical risks. When the length of the syringe 101 needs to be extended, the syringe 101 is first rotated. The piston assembly 1 is threadedly connected to the needle tube 101, allowing the needle tube 101 to extend downwards. Pulling the piston rod 111 upwards extends the piston rod 111, ensuring that the exposure forceps 2 remains effective even after extension. This makes the length of the needle tube 101 adjustable, improving the flexibility and adaptability of the exposure forceps 2. When the exposure forceps 2 needs to be removed, the piston rod 111 is moved downwards to release the clamping plate 21 from fixing the human tissue or internal organs. Then, the piston rod 111 is pulled upwards, and the torsion spring 8 moves the swing plate 4 downwards to reset, thereby improving the reset efficiency of the exposure forceps 2. After the exposure forceps 2 is reset, it is removed. After the surgery, the exposure forceps 2 is cleaned and disinfected in preparation for the next use.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
