Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an ablation needle fixator. Background Art
[0002] During the pulmonary microwave ablation surgery, the stable fixation of the ablation needle is one of the key factors to ensure the success of the surgery and the safety of the patient. The microwave ablation technology uses the thermal effect of high-frequency electromagnetic waves to directly act on the lesion site, causing the diseased tissue to coagulate and necrosis at high temperature, so as to achieve the treatment purpose. This technology has the advantages of wide application range, few complications, small trauma to the patient, and fast recovery, and is especially suitable for patients with cardiopulmonary insufficiency, those who refuse surgery or cannot tolerate surgery.
[0003] However, during the surgery, the stable fixation of the ablation needle has become a technical challenge. Due to factors such as the difference in patient body type, the particularity of the surgical site, and the characteristics of the ablation needle itself (such as the heavier head end), it is often difficult for the ablation needle to maintain a stable position and angle after being inserted into the lesion. This not only increases the surgical difficulty, but also may cause the ablation needle to shift during the surgery, affecting the ablation effect and even increasing the risk of damage to the surrounding tissues of the patient. Therefore, in order to solve the above problems, we propose an ablation needle fixator. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose an ablation needle fixator.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] An ablation needle fixator includes a plastic soft sheet. The top of the plastic soft sheet is installed with a movable sphere through a locking component. The top end of the movable sphere is fixedly installed with a stable tube. A through channel is opened inside the movable sphere, and the channel is communicated with the stable tube;
[0007] A circular hole is opened in the middle of the plastic soft sheet, and an adhesive layer is fixedly installed at the bottom of the plastic soft sheet.
[0008] Further, the locking component includes a locking sleeve and a support ring. The locking sleeve is threadedly installed on the outside of the support ring, and the movable sphere is located inside the locking sleeve.
[0009] Further, the diameter of the movable sphere is greater than the inner diameter of the support ring, and it is located directly above the circular hole.
[0010] Further, a plurality of anti-slip protrusions are fixedly installed on the outer surface of the locking sleeve at equal intervals in a circumferential manner.
[0011] Further, a stabilizing ring is fixedly embedded at the upper end inside the stabilizing tube, and the stabilizing ring is made of silica gel.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] Through the combination of the plastic soft sheet and the adhesive layer, the present utility model realizes a firm fit with the patient's skin, providing a stable foundation for the accurate insertion of the ablation needle. The design of the locking assembly, the stabilizing tube and the movable sphere enables medical staff to adjust the initial angle and position of the ablation needle according to the actual situation before the operation. After the ablation needle is inserted into the lesion, it can maintain an accurate position and angle, effectively preventing the deviation of the ablation needle during the operation, thereby improving the accuracy and safety of the operation.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model;
[0021] Referring to Figures 1-4 , an ablation needle fixator includes a plastic soft sheet 1. The top of the plastic soft sheet 1 is provided with a movable sphere 3 through a locking assembly. The top end of the movable sphere 3 is fixedly installed with a stabilizing tube 4. A through channel is opened inside the movable sphere 3, and the channel communicates with the stabilizing tube 4; a round hole is opened in the middle of the plastic soft sheet 1, and an adhesive layer 7 is fixedly installed at the bottom of the plastic soft sheet 1.
[0022] Before inserting the ablation needle into the patient's body, first paste the plastic soft sheet 1 to the position where the ablation needle needs to be inserted through the adhesive layer 7. Then insert the ablation needle into the stabilizing tube 4. Medical staff can push it into the lesion inserted into the patient's body. After that, the medical staff can fix the movable sphere 3 through the locking assembly. After the movable sphere 3 is fixed, the stabilizing tube 4 will also be fixed accordingly. At this time, the ablation needle can maintain a stable position and angle, effectively avoiding deviation during the operation.
[0023] Both the plastic soft sheet and the adhesive layer can be made of medical-grade sterile materials, ensuring the cleanliness and sterility of the surgical area and reducing the risk of infection.
[0024] The locking assembly includes a locking sleeve 2 and a support ring 5. The locking sleeve 2 is threadedly installed on the outside of the support ring 5. The movable sphere 3 is located inside the locking sleeve 2. The diameter of the movable sphere 3 is larger than the inner diameter of the support ring 5. The support ring 5 is located directly above the circular hole.
[0025] When the locking sleeve 2 is in the unlocked state, there is a certain gap between the inner wall of the locking sleeve 2 and the movable sphere 3, allowing the movable sphere 3 to rotate. At this time, the orientation of the stabilizing tube 4 can be adjusted arbitrarily.
[0026] When the locking sleeve 2 is in the locked state, a part of the inner wall of the locking sleeve 2 is in close contact with a part of the outer wall of the movable sphere 3. The movable sphere 3 will be clamped by the locking sleeve 2 and the support ring 5, and the movable sphere 3 will not be able to rotate. At this time, the stabilizing tube 4 is in a fixed state and its orientation cannot be adjusted.
[0027] A plurality of anti-slip protrusions are fixedly installed on the outer surface of the locking sleeve 2 at equal intervals in a circumferential manner. The setting of the anti-slip protrusions can increase the friction between the user's hand and the outer surface of the locking sleeve 2, facilitating the rotation of the locking sleeve 2.
[0028] A stabilizing ring 6 is fixedly embedded at the upper end inside the stabilizing tube 4. The stabilizing ring 6 is made of silica gel. After the ablation needle is inserted into the inside of the stabilizing tube 4, the stabilizing ring 6 can be sleeved on the outer surface of the ablation needle. The stabilizing ring 6 will be clamped between the stabilizing tube 4 and the ablation needle. The setting of the stabilizing ring 6 can prevent the ablation needle from shaking slightly inside the stabilizing tube 4, further improving the stability of the ablation needle.
