Technical Field

[0001] This invention discloses a puncture assistance device for ventricular puncture and drainage and its usage method, which relates to the technical field. Background Technology

[0002] Ventricular puncture is a surgical procedure performed by creating an opening in the skull to perform appropriate treatment or examination. Unlike craniotomy, ventricular puncture typically only requires a small hole to be made in the skull using a skull drill to reach the dura mater, through which a needle is then inserted to reach the pathological site. One application of ventricular puncture is drainage. This requires a continuous external drainage device. In clinical practice, a simple cranial drainage device is sometimes created by sterilizing an empty IV bottle and inserting a blood transfusion set. However, this method carries the risk of cerebrospinal fluid reflux leading to intracranial infection, or infection due to inadequate sterilization.

[0046] In order to more clearly illustrate the technical solutions of the embodiments of the application, the application will be described in detail below with reference to the drawings. Embodiment 1

[0047] Brain ventricle puncture may only rely on manual control by medical staff, which may cause instability such as shaking during puncture. In the prior art, a puncture is assisted by a disc structure with holes at the puncture position, but in some cases the angle may not completely conform to the control direction of the disc structure, so the applicant increases the angle adjustment function on the premise of applying fixation.

[0048] The brain ventricle puncture drainage puncture auxiliary device described in the embodiment includes a reference element 1 and a puncture needle ring fastener 2. The reference element 1 and the puncture needle ring fastener 2 are both center-opening sheet structures. The reference element 1 is fixed on the head. The puncture needle ring fastener 2 is axially coincident with the center opening of the reference element 1 and the diameter difference is less than 1 mm.

[0049] The reference fixing member can be adhesively fixed on the head, the reference member 1 provides a basic fixing force for each of the remaining components, and therefore in some embodiments, the fixing member can also be provided with an extension 201 to be fixed on the head.

[0050] The puncture needle ring member 2 extends with an extension 201 having a curved structure, the reference member 1 is provided with a groove 102 matching the extension 201, and the extension 201 and the groove 102 form a fixed structure after matching to connect and fix the reference member 1 and the puncture needle ring member 2.

[0051] The applicant considers that sufficient stability needs to be ensured during brain puncture, and therefore the extension 201 and the groove 102 should form a complete fixed structure between the fixing member after connection. Based on this, in the present embodiment, the extension 201 includes two parts, one part is connected between the puncture needle ring member 2 body and the free rotating member 202, and the other part includes a locking member 205, the locking member 205 is an active structure, and when the locking member 205 is active to lock the puncture needle ring member 2, the free rotating member 202 no longer rotates.

[0052] Compared with the prior art, the device ensures the overall fixation of the device based on the fixing member, and the puncture needle ring member 2 provides a reference for the puncture needle, so that the position of the puncture needle will not be offset due to accidental shaking of medical staff or other conditions, and the device has more reliable stability in actual operation. Embodiment 2

[0053] Based on the content of embodiment 1, the applicant considers that after fixing the reference member 1 to obtain a reference, the puncture needle ring member 2 needs to be connected thereto, and the present embodiment discloses a specific implementation manner, which is of course not the only one.

[0054] In the present embodiment, the reference member 1 and the puncture needle ring member 2 are disc-shaped structures, the groove 102 is an annular groove, the annular groove is provided with a notch 101 through which the extension 201 passes, and the extension 201 is inserted into the notch 101 and rotated to form a fixed structure with the groove 102.

[0055] The inner wall of the groove 102 is provided with a one-way locking piece, the one-way locking piece is a small piece connected by an elastic member, and the small piece can only rotate in the rotation direction of the extension 201 under the action of the elastic member.

[0056] In combination Figures 1-2To understand, the extension 201 is a small piece of bending type, which is in contact with the inclined surface of the small piece after rotating to the small piece position, and the force condition of the small piece after rotation allows the extension 201 to pass, and after passing, the extension 201 is limited in the space of the small piece and the groove 102 that just fixes the extension 201. Embodiment 3

[0057] The content in Embodiment 2 has explained that the application in this embodiment can realize the connection between the reference element 1 and the puncture needle ring fixing element 2, and in combination with the content of Embodiment 1, the applicant describes in detail how to realize the angle adjustment function after connection in this embodiment.

[0058] The locking element 205 is a curved rod, one end of which is a bending structure matching the groove 102, and the other end is a clamping structure provided with a through threaded rod 204, and the puncture ring fixing element further comprises a second protruding part 203 matching the clamping structure, and after the second protruding part 203 is matched with the clamping structure, the threaded rod 204 moves to the top of the second protruding part 203.

[0059] In this embodiment, the locking element 205 limits the movement of the puncture needle ring fixing element 2 by screwing, and the puncture needle ring fixing element 2 can be fixed with the reference element 1 by the small piece involved in Embodiment 2, and after being fixed, the small piece is rotationally connected thereto. The purpose is to adjust the puncture angle according to the actual situation, and the applicant considers that after the angle of the puncture ring fixing element changes, the pressure in a single direction cannot ensure fixation, so in some embodiments, the puncture ring fixing element further comprises a second protruding part 203 matching the clamping structure.

[0060] In combination with Figure 3 To understand, the second protruding part 203 is a rectangular small piece in this embodiment, and the clamping structure adjusts the angle and engages with the rectangular small piece. The rod body connected with the clamping structure is naturally a bendable rod body, and in some specific embodiments, a part that limits the rotation of the rod body needs to be added, that is, after the angle adjustment is completed, the angle change is limited to complete the fixation.

[0061] In other embodiments, the bending part of the curved rod is provided with a through hole, and after an irregular rod body is inserted into the through hole, the rotation of the curved rod is limited.

[0062] The device in this embodiment can determine the angle of the puncture needle ring fixing element 2 according to different puncture conditions, and can realize the clamping function of the clamping structure by screwing the threaded rod 204, and fix the structure after the angle adjustment is completed through the clamping structure. Compared with the prior art, the application in this embodiment has the angle adjustment function under the premise of ensuring stability. Embodiment 4

[0063] In fact, in addition to the fixation problem during the puncture process, the problem of isolation from the outside world to avoid infection should also be considered during the ventricle puncture process. Therefore, based on the structure of the device in the preceding embodiment, the structure in this embodiment also includes the following structure:

[0064] The reference element 1 also includes a skull trepanation drill ring fixture 3, which is a thin sheet structure with a central opening. A rubber film 4 is arranged in the central opening of the skull trepanation drill ring fixture. The rubber film 4 has a through hole in the center, which is a micropore with a diameter of less than 0.1 mm under no force.

[0065] The puncture needle ring fixture 2 has a central opening with a diameter of 0.7-1 cm in the reference element 1. The puncture needle ring fixture 2 has a rubber film arranged in the central opening, which completely seals the central opening.

[0066] It is not difficult to understand that the skull trepanation drill fixture and the puncture needle ring fixture 2 both have the function of isolating bacteria to prevent infection. The rubber film 4 of the skull trepanation drill fixture will seal the space around the drill bit when the drill bit passes through. After the drill bit is removed, due to its own elasticity, it will only include a very small micropore, effectively preventing infection due to wound retention during the operation.

[0067] In addition, the puncture needle ring fixture 2 completely isolates the wound by using the rubber film 4. In the case of using the skull trepanation drill ring fixture 3, after the drill bit is removed, the puncture needle ring fixture 2 is connected to the reference element 1. At this time, the film 4 of the puncture needle ring fixture 2 seals the wound inside. The puncture device pierces the film 4 to explore the brain, achieving the purpose of complete bacterial isolation. Embodiment 5

[0068] In order to further improve the safety and stability of the device based on embodiments 1-4, in this embodiment, the puncture needle ring fixture 2 also includes a depth testing element 6 and a brake element 5 arranged inside. The depth testing element 6 detects the depth of the puncture needle. The depth testing element 6 is connected with an alarm element. The brake element 5 is a clamping structure arranged in the puncture needle fixture.

[0069] In combination Figure 6 , the depth testing element 6 can be a rotating disc with a protruding structure. The rotating disc rotates with the puncture needle passing through the channel and records the depth of penetration. Specifically, when the depth of the puncture needle exceeds a safe value, the depth testing element sends an alarm, and the brake element 5 works to clamp the puncture needle. The safe value can be pre-set according to different situations.

[0070] In combination with the foregoing embodiments, the present embodiment discloses a method for using the ventricle puncture and drainage puncture auxiliary device. In the specific embodiment, the skull drilling ring fastener 3 is not used, and the method specifically comprises the following steps:

[0077] Step 4, puncture

[0078] Adjust the angle of the puncture needle ring fastener 2 according to the puncture needs, and complete the puncture through the puncture needle ring fastener 2.

[0079] In another specific embodiment, the skull drilling ring fastener 3 is used, and the method specifically comprises the following steps:

[0084] Step 3, drilling the skull,

[0085] Drill the skull using the skull brick;

[0086] Step 4, connecting the reference element 1 and the puncture needle fixing ring

[0087] After the extension 201 is connected and fixed with the groove 102, the reference element 1 is connected with the puncture needle ring fastener 2;

[0088] Step 5, puncture

[0089] The angle of the needle ring fastener 2 is adjusted according to the need of puncture, and the puncture needle is used to complete the puncture through the needle ring fastener 2.

[0090] The above is only part of the embodiments of the application, and does not limit the application in any form. Any simple modification, equivalent change and modification made to the above embodiments still belongs to the protection scope of the technical scheme of the application.
