Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a brush-equipped femoral nozzle for a pulse flushing gun. Background Technology

[0002] In the medical field, pulse irrigation guns are often used to clean wound tissues. The pulsed water jets sprayed by the pulse irrigation gun with a certain pressure cause bacteria, foreign objects and other debris in the wound to be separated from the tissue by the bouncing action, thus achieving the purpose of thorough wound cleaning.

[0003] In clinical irrigation procedures, the rinsing of bone debris from the medullary cavity wall is typically performed using a femoral spray nozzle with a brush, simultaneously rinsing and brushing the medullary cavity wall. Existing femoral spray nozzles usually have soft brush heads. However, due to the insufficient rigidity of these soft brush heads, the bone debris in the medullary cavity wall may not be thoroughly rinsed, especially for necrotic tissue within the medullary cavity wall. In such cases, the soft brush head is essentially ineffective at removing necrotic tissue from the medullary cavity wall, thus failing to achieve the desired surgical effect. Furthermore, during repeated rinsing, the brush teeth on the soft brush head may break and fall into the medullary cavity, causing inconvenience during the procedure. Utility Model Content

[0004] The purpose of this invention is to provide a brush-equipped femoral nozzle for a pulse flushing gun, which has a strong structure and can thoroughly clean and sweep out bone debris from the medullary cavity.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0006] A brush-equipped femoral spray head for a pulse irrigation gun includes a mounting connector for installation on the pulse irrigation gun. The mounting connector is connected to a spray tube and a suction tube. The spray tube is located inside the suction tube, and the inner diameter of the suction tube is larger than the outer diameter of the spray tube. A rigid brush head is located at the end of the suction tube away from the mounting connector, and rigid brush teeth are provided on the outer wall of the rigid brush head. The rigid brush head is made of a hard material, such as metal. Its function is to effectively sweep out bone debris from the medullary cavity while preventing the brush teeth from breaking, and it is convenient to use.

[0007] Furthermore, the rigid brush teeth are frustum-shaped, and their cross-sectional area gradually decreases along the axial direction away from the suction tube. This design prevents bone debris from getting stuck between adjacent brush teeth, facilitating cleaning.

[0008] Furthermore, the outer wall of the rigid brush head is uniformly distributed with multiple layers of rigid brush teeth along its own axial direction, and each layer of rigid brush teeth has multiple rigid brush teeth evenly distributed around the axis of the rigid brush head. Its function is to enhance the cleaning ability of the rigid brush head through the distribution design of the rigid brush teeth, and to allow steel wires to be wound and bound or helical springs to be screwed in between the rigid brush teeth, thereby fixing the steel wires or helical springs and further enhancing the scrubbing ability.

[0009] Furthermore, the end of the spray pipe furthest from the mounting joint is equipped with a spray head, and the side wall of the spray head is provided with a spray port that communicates with the spray pipe. Its function is to allow the cleaning fluid to be sprayed into the bone marrow cavity through the spray port.

[0010] Furthermore, along the length of the spray tube, the spray nozzle is located outside the rigid brush head. This design, through the spatial relationship between the spray nozzle and the rigid brush head, prevents the rigid brush head from blocking the water flow from the spray nozzle, thereby avoiding a decrease in flushing intensity due to reduced pressure from the water flow impacting the bone marrow cavity wall.

[0011] Furthermore, the end of the spray head facing the spray pipe is provided with a spray mounting boss, the outer diameter of which is equal to the inner diameter of the spray pipe. The spray pipe is sealed to the spray mounting boss.

[0012] Furthermore, the spray nozzle is square in shape, and four spray nozzles are evenly distributed in a ring on the side wall of the spray head.

[0013] Furthermore, the spray pipe and the suction pipe are coaxially arranged.

[0014] Furthermore, the mounting connector has a separate inlet and outlet at the end opposite to the suction pipe. The mounting connector also has a spray pipe mounting hole for mounting the spray pipe, which communicates with the inlet. At the end of the mounting connector facing the suction pipe, there is a suction pipe mounting hole coaxially arranged with the spray pipe mounting hole. The mounting connector has a connecting cavity, and the outlet, suction pipe mounting hole, and spray pipe mounting hole are all connected to this connecting cavity. The spray pipe and the suction pipe are sealed together.

[0015] Furthermore, the rigid brush head has a suction mounting boss at the end facing the suction tube. The outer diameter of the suction mounting boss is equal to the inner diameter of the suction tube, and the inner diameter of the suction mounting boss is larger than the outer diameter of the spray tube. The suction tube and the suction mounting boss are sealed together.

[0016] The beneficial effects of this utility model are:

[0017] 1. The rigid brush head design effectively removes bone fragments from the medullary cavity while preventing the brush teeth from breaking, making it easy to use.

[0018] 2. The rigid brush tooth shape design prevents bone fragments from getting stuck between adjacent rigid brush teeth, making cleaning easier;

[0019] 3. By designing the spatial relationship between the spray nozzle and the rigid brush head, the rigid brush head can be prevented from blocking the water flow from the spray nozzle, thereby avoiding a decrease in the flushing intensity caused by the reduced pressure of the water flow impacting the bone marrow cavity wall.

[0031] Specifically, such as Figure 5 As shown, the rigid brush teeth 5 are frustum-shaped, and the cross-sectional area of ​​the rigid brush teeth 5 gradually decreases along the axial direction away from the suction tube 3. Their function is to prevent bone debris from getting stuck between adjacent rigid brush teeth 5 through the design of the rigid brush teeth 5, facilitating cleaning.

[0032] Specifically, such as Figure 5 As shown, the rigid brush head 4 has multiple layers of rigid brush teeth 5 evenly distributed along its own axial direction on its outer wall. Within each layer of rigid brush teeth 5, multiple rigid brush teeth 5 are evenly distributed around the axis of the rigid brush head 4. Its function is to enhance the cleaning ability of the rigid brush head 4 through the distribution design of the rigid brush teeth 5. Simultaneously, it allows for the wrapping and binding of steel wires or the rotational screwing of helical springs into the gaps between the rigid brush teeth 5, thus fixing the steel wires or helical springs and further enhancing the scrubbing ability.

[0033] Specifically, such as Figure 2 , Figure 4 As shown, the end of the spray pipe 2 furthest from the mounting joint 1 is provided with a spray head 6, and the side wall of the spray head 6 is provided with a spray port 7 that communicates with the spray pipe 2. Its function is to spray the cleaning fluid into the bone marrow cavity through the spray port 7.

[0034] Specifically, such as Figure 1As shown, along the length of the spray tube 2, the spray nozzle 7 is located outside the rigid brush head 4. Its function is to prevent the rigid brush head 4 from blocking the water flow from the spray nozzle 7, thereby avoiding a decrease in flushing intensity due to reduced pressure from the water flow impacting the bone marrow cavity wall.

[0035] Specifically, such as Figure 4 As shown, the spray head 6 has a spray mounting boss 8 at one end facing the spray pipe 2, and the outer diameter of the spray mounting boss 8 is equal to the inner diameter of the spray pipe 2. The spray pipe 2 is bonded to the spray mounting boss 8.

[0036] Specifically, such as Figure 4 As shown, the spray nozzle 7 is square in shape, and four spray nozzles 7 are evenly distributed in a ring on the side wall of the spray head 6.

[0037] Specifically, such as Figure 1 As shown, the spray pipe 2 and the suction pipe 3 are coaxially arranged.

[0038] Specifically, such as Figure 3 As shown, the mounting connector 1 has a separate inlet and outlet at the end facing away from the suction pipe 3. The mounting connector 1 has a spray pipe mounting hole 11 for mounting the spray pipe 2, which is connected to the inlet. The mounting connector 1 also has a suction pipe mounting hole 12 at the end facing the suction pipe 3, which is coaxial with the spray pipe mounting hole 11. The mounting connector 1 has a connecting cavity 13, through which the outlet, suction pipe mounting hole 12, and spray pipe mounting hole 11 are all connected. The spray pipe 2 is bonded to the spray pipe mounting hole 11, and the suction pipe 3 is bonded to the suction pipe mounting hole 12.

[0039] Specifically, such as Figure 5 As shown, the rigid brush head 4 has a liquid suction mounting boss 14 at the end facing the liquid suction tube 3.

The liquid suction tube 3 is bonded to the liquid suction mounting boss 14.

[0040] The working principle of this embodiment is explained as follows: First, the mounting connector 1 is installed on the pulse flushing gun, so that the flushing fluid outlet of the pulse flushing gun is connected to the inlet on the mounting connector 1, and the recovery fluid inlet of the pulse flushing gun is connected to the outlet on the mounting connector 1. The pulse flushing gun inputs the flushing fluid into the inlet. The flushing fluid is sprayed through the spray pipe 2 and sprayed through the spray nozzle 7 onto the inner wall of the bone marrow cavity to clean the bone debris. At the same time, the suction pipe 3 is moved to drive the rigid brush head 4 to reciprocate to clean the bone marrow cavity. When the spray nozzle 7 can clean the bone marrow cavity at different depths, the rigid brush teeth 5 can sweep out the bone debris. The recovered fluid after flushing is sucked into the outlet through the suction pipe 3 and then enters the recovery fluid inlet on the pulse flushing gun.
