Description

Technical Field

[0001] This utility model relates to the field of human life necessities, and in particular to medical auxiliary equipment, especially a multi-level cerebral cavity-peritoneal cavity bypass strip. Background Technology

[0002] Cerebral-peritoneal shunt surgery is a common neurosurgical procedure and a classic surgical method for treating hydrocephalus. The procedure involves surgically inserting an adjustable shunt tube into the ventricle of the brain and the peritoneum. Based on changes in intracranial pressure, the shunt is connected via subcutaneous tunnels in the head and chest to drain the hydrocephalus into the peritoneum for treatment. The establishment of the subcutaneous tunnel requires the use of a shunt tube.

[0003] In the existing technology, there are two types of duct strips:

[0004] One type is a solid tube, which is hard in texture. When using it, the surgeon holds the tube by the handle and passes it through the incision in the head, down behind the ear, through the neck, and under the skin of the chest. It then exits through the skin incision below the xiphoid process. The tip of the silicone drainage tube is passed through the perforation at the conical end and ligated. The surgeon then pulls out the tube, and the silicone drainage tube is inserted into the subcutaneous tissue to complete the subcutaneous tunnel placement. For example, the ventriculoperitoneal shunt tube disclosed in CN202604904U belongs to this type of tube.

[0005] One type is a hollow tube. When using it, the surgeon holds the tube by the gripping part and passes it through the incision in the head, down behind the ear, through the neck, and under the skin of the chest. After exiting through the skin incision below the xiphoid process, a drainage tube is inserted into the core of the tube. The tube is then removed, and the drainage tube is guided from the abdominal cavity to the ventricle. For example, a subcutaneous tunnel tube disclosed in CN202446142U belongs to this type of tube.

[0006] Both of these types of scouring pads have certain drawbacks:

[0007] 1. The disadvantage of solid tubes is that they cannot be inserted into the subcutaneous tunnel in one go, and the process of removing the tube can easily cause secondary damage to the tissues around the subcutaneous tunnel.

[0008] 2. The disadvantage of hollow tubes is that the tube wall is thin due to the hollow tube structure. Therefore, the tube is not firm enough during puncture and is easy to bend when it encounters tough tissue. The operation of subcutaneous passage is very difficult, the operation time is prolonged, the patient suffers pain, and the quality of the operation is affected.

[0009] 3. In addition, the length of the cleaning rod in the existing technology is usually fixed. People of different ages or body shapes need to buy cleaning rods of different sizes. However, a single cleaning rod is expensive, and buying multiple cleaning rods is costly. For example, a Medtronic cleaning rod costs about 1,400 yuan. Summary of the Invention

[0010] The purpose of this utility model is to provide a multi-stage cerebral-peritoneal shunt strip, which aims to solve the technical problems in the prior art where solid strips are inconvenient for drainage tube insertion, hollow strips are easy to bend and inconvenient for subcutaneous passage, and people of different ages or body shapes need to purchase strips of different specifications and sizes.

[0011] A multi-stage cerebral-peritoneal shunt strip includes a strip body, a handle, an extension tube, and a puncture head. The rear end of the strip body is detachably connected to the front end of the handle, the front end of the strip body is detachably connected to the rear end of the extension tube, and the front end of the extension tube is detachably connected to the rear end of the puncture head. The front end of the puncture head is a puncture tip, and a self-tapping thread is provided on the side wall of the front end of the puncture head. The strip body and the extension tube are both tubular. A guide tube extending from front to back is provided inside the handle. The diameter of the rear end of the guide tube is larger than the diameter of the front end of the guide tube, and the diameter of the guide tube gradually narrows from the rear end to the front end. The guide tube, the strip body, and the extension tube are coaxially connected in sequence. The gripping part of the handle is disc-shaped, and the axis of the disc-shaped gripping part coincides with the axis of the guide tube.

[0012] Furthermore, it includes two or more extension tubes connected end to end, with the front end of any extension tube being detachably connected to the rear end of other extension tubes.

[0013] Furthermore, universal buckles are provided at the rear end of the main body of the piercing rod, the rear end of the extension tube, and the rear end of the piercing head; universal slots are provided on the front end of the handle, the front end of the main body of the piercing rod, and the front end side wall of the extension tube; any universal buckle can engage with any universal slot; the universal buckle engages with the universal slot from the inside of the universal slot.

[0014] Furthermore, it includes a dedicated unlocking clip, which is a U-shaped spring clip with two clamping arms. The inner sides of the two clamping arms are respectively provided with teeth. The teeth are inserted into the universal slot from the outside of the tube and abut against the teeth of the universal buckle.

[0015] The working principle of this utility model:

[0016] During assembly, this invention allows for the connection of multiple extension tubes between the puncture head and the main body of the puncture tube, depending on the patient's age and body size. During puncture, when encountering tough tissue, the grip can be slowly rotated, allowing the self-tapping threads on the puncture head to self-tackle under the skin, avoiding direct force that could cause the puncture tube to bend, deform, or be damaged.

[0017] Compared with existing technologies, the advantages of this invention are positive and obvious:

[0018] 1. The main body and extension tube of this utility model are tubular hollow tubes, and the piercing head has self-tapping threads. When encountering relatively tough human tissue, it can slowly rotate and then self-tap and pierce, avoiding direct force piercing that would cause the tube to bend, deform or be damaged.

[0019] 2. The extension tube of this utility model can be connected end to end in multiple tubes according to the patient's age and body size, thereby expanding the applicability of the tube and reducing the cost of purchasing tubes of various specifications.

[0020] 3. The handle, the main body of the scalpel, the extension tube, and the puncture head of this utility model are all detachable, which facilitates disinfection and sterilization.

[0021] 4. The handle of this utility model is provided with a guide pipe, and the guide pipe, the main body of the guide bar, and the extension pipe are coaxially connected in sequence. The drainage pipe is inserted straight through, without the need for silk thread, suction device or other guides.

[0022] 5. The universal buckle of this utility model is tightly connected from the inside of the universal slot, making it difficult to fall off. After connection, there is no protrusion on the outer wall of the tube, keeping the puncture smooth. It can be unlocked by a special unlocking clip or medical tweezers. Attached Figure Description

[0030] The following embodiments will further illustrate the present invention, but do not limit the present invention.

[0031] like Figures 1 to 6 As shown, this embodiment provides a multi-stage cerebral-peritoneal shunt strip, including a strip body 1, a handle 2, an extension tube 4, and a puncture head 3. The strip body 1, the extension tube 4, and the puncture head 3 are all made of medical stainless steel, and the handle 2 is made of ring-sterilizable plastic. The handle 2, the strip body, the extension tube 4, and the puncture head 3 can all be disassembled to facilitate disinfection and sterilization after disassembly.

[0032] The rear end of the main body 1, the rear end of the extension tube 4, and the rear end of the puncture head 3 are all provided with universal buckles 5; the front end of the handle 2, the front end of the main body 1, and the front end of the extension tube 4 are provided with universal slots 6; any universal buckle 5 can be engaged with any universal slot 6, thereby making the rear end of the main body 1 detachably connected to the front end of the handle 2, the front end of the main body 1 detachably connected to the rear end of the extension tube 4, and the front end of the extension tube 4 detachably connected to the rear end of the puncture head 3.

[0033] Specifically, the universal buckle 5 includes two teeth. The inner ends of the teeth of the universal buckle 5 are fixed to both sides of the inner wall of the rear end of the main body 1, the rear end of the extension tube 4, or the rear end of the piercing head 3. The outer ends of the teeth of the universal buckle 5 extend out of the tube. The universal slot 6 includes two through slots, which are symmetrically opened on both sides of the front end of the handle 2, the front end of the main body 1, and the front end side wall of the extension tube 4. The universal buckle 5 at the rear end of the main body 1, the rear end of the extension tube 4, or the rear end of the piercing head 3 is inserted into the tube from the inner side of the front end of the handle 2, the front end of the main body 1, or the front end of the extension tube 4, and engages with the universal slot 6 at the corresponding position, thereby achieving a detachable connection.

[0034] During connection, all universal clips 5 are tightly engaged with the corresponding universal slot 6 from the inside of the tube. After connection, there are no protrusions on the outer wall of the tube, making it difficult to fall off during puncture and keeping the puncture smooth. When unlocking, it can be unlocked by a special unlocking clip 7 or medical tweezers.

[0035] The main body 1 and extension tube 4 of the tube are both tubular. The handle 2 has a guide tube 201 that runs through the front and back. The diameter of the rear end of the guide tube is larger than the diameter of the front end of the guide tube 201. The diameter of the guide tube 201 gradually narrows from the rear end to the front end, so as to facilitate the introduction of the drainage tube into the tube. The guide tube 201, the main body 1 of the tube, and the extension tube 4 are coaxially connected in sequence.

[0036] The front end of the puncture head 3 is a puncture tip, which is bullet-shaped. The side wall of the front end of the puncture head 3 is provided with a self-tapping thread 301. The grip part 202 of the handle 2 is disc-shaped. The axis of the disc-shaped grip part 202 coincides with the axis of the guide tube 201. The disc-shaped grip part 202 is easier to rotate, thereby driving the puncture head 3 to rotate through the main body 1 and the extension tube 4. When encountering relatively tough human tissue, the grip part 202 can be rotated slowly, so that the self-tapping thread 301 on the puncture head 3 can perform self-tapping puncture under the skin, avoiding direct force puncture that may cause the tube to bend, deform or be damaged.

[0037] It includes two or more extension tubes 4 connected end to end. The front end of any extension tube 4 can be detachably connected to the rear end of other extension tubes 4. Multiple extension tubes 4 can be connected end to end according to the patient's age and body size, thereby increasing the applicability of the tube and reducing the cost of purchasing tubes of various specifications.

[0038] It includes a dedicated unlocking clip 7, which is a U-shaped spring clip with two clamping arms 701. The inner sides of the two clamping arms 701 are respectively provided with teeth 702. The teeth 702 are inserted into the universal slot 6 from the outside of the tube and abut against the teeth of the universal buckle 5. Thus, by squeezing the clamping arms 701 inward, the teeth of the universal buckle 5 are pushed out of the universal slot 6, thereby achieving quick unlocking.

[0039] How to use this embodiment:

[0040] Before use, the tubes are assembled. Depending on the patient's age and body size, multiple extension tubes 4 need to be connected end to end between the tube body and the puncture head 3. Then, the operator holds the tube handle 202 and passes it through the subcutaneous tissue of the head incision, behind the ear, neck, and chest to create a subcutaneous tunnel. After exiting through the skin incision below the xiphoid process, a drainage tube is inserted into the inner core of the tube. The puncture head 3 is removed using a special unlocking clamp 7 or medical forceps, the tube is withdrawn, and the drainage tube is guided from the abdominal cavity end to the ventricular end.

[0041] During the puncture process, when encountering relatively tough human tissue, the grip 202 can be slowly rotated, so that the self-tapping thread 301 on the puncture head 3 can perform self-tapping puncture under the skin, avoiding direct force puncture that could cause the tube to bend, deform or be damaged.

[0042] This embodiment requires disinfection and sterilization after use, and can only be reused after meeting medical standards.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
