Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a back-patting handle for knee joint surgery. Background Technology

[0002] In knee replacement surgery, the back-camera handle is used to connect various fitting components, such as bone chisels and removal devices, enabling precise insertion into the bone or rapid removal of the prosthesis. It plays a crucial role in knee revision surgery. However, existing back-camera handles have the following drawbacks:

[0003] Excessive weight: Traditional handles are mostly made of solid metal, which can easily lead to hand fatigue for doctors and affect the accuracy of operation after prolonged use.

[0004] Poor anti-slip performance: The surface is smooth or only has simple textures, and it is easy to slip off after being contaminated with blood or saline during the operation, which poses a safety hazard.

[0005] The striking surface is poorly designed: the striking surface is mostly flat or slightly curved, resulting in uneven stress distribution and easy deformation of the handle.

[0006] Low grip comfort: The handle has a simple shape and does not conform to the anatomical structure of the hand, which can easily cause muscle strain during prolonged use.

[0007] Insufficient adaptability: Specialized tools are required to switch between striking and removing functions, which prolongs the operation time. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide a back-palm handle for knee joint surgery, which achieves multifunctional and highly reliable operation through ergonomic design.

[0009] This utility model is achieved through the following solution:

[0010] A back-tap handle for knee joint surgery includes a back-tap handle body and a quick-connect system located at the rear end of the back-tap handle body. The back-tap handle body includes a grip portion and a striking portion located at the front end of the grip portion. The grip portion is provided with multiple hollow through slots. The striking portion is an arc-shaped striking surface with a diameter larger than that of the grip portion. A biomimetic grip groove is provided at the connection between the back of the arc-shaped striking surface and the grip portion.

[0011] Furthermore, the plurality of the hollowed-out slots are inclined inward, and the cross-sectional area of ​​the hollowed-out portion in the middle of the hollowed-out slot is the smallest.

[0012] Furthermore, the multiple hollowed-out channels adopt a segmented design.

[0013] Preferably, all of the aforementioned hollowed-out slots are teardrop-shaped structures.

[0014] Furthermore, the grip section has anti-slip grooves between multiple hollow slots.

[0015] The optimized anti-slip groove has a depth of 0.5 mm.

[0016] The optimized back grip is made of stainless steel and cut into one piece.

[0017] The optimized design connects the back grip body to the quick-connect system via pins.

[0018] Beneficial effects of the utility model:

[0019] The back-palm handle for knee joint surgery provided by this utility model has the following advantages:

[0020] 1. The grip section adopts a hollow structure, which reduces weight compared to the traditional solid handle, facilitates disinfection, and reduces hand fatigue for doctors.

[0021] 2. The anti-slip grooves increase the coefficient of friction, which provides a more stable grip in both dry and wet environments and reduces the risk of the instrument slipping compared to traditional surface knurling treatments.

[0022] 3. Using an arc-shaped striking surface with a diameter larger than the grip can enhance the striking effect, increase safety, and prevent accidents caused by misaligned striking during operation.

[0023] 4. The biomimetic grip groove conforms better to the curves of the human hand and fingers, increasing grip comfort, reducing doctor fatigue, and improving operational efficiency and stability;

[0024] 5. It adopts a quick-connect system, which is highly compatible and can quickly switch between different matching parts, improving surgical efficiency. Attached Figure Description

[0028] A schematic diagram of a back-palm handle for knee surgery is shown below. Figure 1 , Figure 2As shown, the back handle body includes a back handle main body and a quick-connect system 1 located at the rear end of the back handle main body. The back handle main body includes a grip part 4 and a striking part 5 located at the front end of the grip part. The grip part is provided with multiple hollow through grooves 3. The striking part is an arc-shaped striking surface with a diameter larger than that of the grip part, and a bionic grip groove 6 is provided at the connection between the back of the arc-shaped striking surface and the grip part.

[0029] The grip part of the back-tap handle has multiple hollowed-out slots, which can reduce weight, reduce doctor's hand fatigue, and facilitate preoperative tool disinfection to avoid the residue of contaminants.

[0030] The striking part is an arc-shaped striking surface with a diameter larger than that of the grip part, which can increase the striking force and improve safety during striking, avoiding accidents caused by misalignment during operation.

[0031] The connection between the back of the curved striking surface and the grip is provided with a bionic grip groove, which can be set as a double C-shaped arc groove. The depth is adapted to the curve of the adult's palm and fingers to achieve zero-pressure grip, increase grip comfort, reduce the doctor's fatigue index, and when striking the back of the clapper handle, it can be held in the middle of the grip or in the bionic grip groove. Holding in the bionic grip groove can prevent slippage and instability, thus improving the efficiency and stability of operation.

[0032] A quick-connect system is set at the rear of the back-mounted handpiece, which has strong compatibility and can quickly switch between different matching parts, thereby improving surgical efficiency.

[0033] Furthermore, the multiple hollowed-out slots are inclined inwards, and the cross-sectional area of ​​the hollowed-out portion in the middle of the hollowed-out slot is the smallest. This arrangement can ensure that the hollowed-out slots are symmetrical and interconnected, and can ensure the strength of the back handle body while minimizing weight, making it less prone to breakage.

[0034] Furthermore, the multiple hollowed-out slots adopt a segmented design, which can further ensure the strength of the back handle body and prevent the back handle body from breaking.

[0035] Preferably, all of the aforementioned perforated slots are teardrop-shaped structures with relatively smooth edges to avoid stress concentration.

[0036] Furthermore, the gripping part is provided with anti-slip grooves 2 between multiple hollow through slots, which increases the coefficient of friction to achieve stable grip in dry and wet environments and prevent slippage due to blood or saline solution on the hands during surgery.

[0037] The optimized anti-slip grooves are 0.5 mm deep, which not only provide an anti-slip effect but also ensure the strength of the back handle body.

[0038] The optimized back handle is made of stainless steel and cut into one piece, making it easy and quick to manufacture and highly corrosion resistant.

[0039] The optimized design features a pin-connected back grip body to the quick-connect system, making assembly convenient and quick.

[0040] In summary, the back-palm handle for knee joint surgery proposed in this utility model is lightweight, easy to disinfect, reduces the doctor's fatigue index, facilitates stable grip in dry and wet environments, and improves operational efficiency and stability.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
