Description

Technical Field

[0001] The utility model relates to oral medical devices, in particular to a nail extractor with a fixing function. Background Art

[0002] Dental implant surgery is one of the very common surgeries in oral treatment. During dental implant surgery, it is often encountered that the alveolar bone mass of the patient is insufficient and dental implantation cannot be performed. In this case, bone augmentation surgery is required, and membrane nails and membrane nail tools are often used in bone augmentation surgery. For a long time, there has been a relatively complete set of membrane nail tools, and the nail extractor is one of them.

[0003] Bone augmentation surgery often requires the use of absorbable biofilms. This film is covered on the treatment site during treatment. Usually, membrane nails are used to fix the biofilm. After osteogenesis, the biofilm is absorbed and the membrane nails need to be removed. In this case, a nail extractor is required. The head of the nail extractor is usually flat, with an opening at the head end. The opening is inserted under the membrane nail cap, and the membrane nail is pried out using the lever principle.

[0004] When using the existing nail extractor, the membrane nail is likely to fly out due to excessive prying force. The membrane nail is a very small treatment instrument, usually with a maximum diameter of only 2.5 mm and a length usually only 3 mm - 6 mm. The removed membrane nail belongs to medical waste. Flying out easily injures the doctor's eyes or falls to the ground and is impossible to find. In either case, it is likely to pose a safety hazard. Content of the Utility Model

[0005] The utility model provides a nail extractor with a fixing function, aiming to solve the problem that the existing nail extractor is likely to cause the membrane nail to fly out during the nail extraction process.

[0006] To achieve the above object, an embodiment of the utility model provides a nail extractor with a fixing function, including:

[0007] A handle, with a nail extraction head rod provided at one end. The proximal end of the nail extraction head rod is fixed to the handle, and a pressing plate and a nail extraction plate are provided at the distal end. The nail extraction plate and the pressing plate are arranged at intervals on the nail extraction head rod. The distance between the nail extraction plate and the pressing plate is less than or equal to the thickness of the membrane nail cap. A notch is provided at the distal end of the nail extraction plate, and the notch extends from the distal end of the nail extraction plate towards the proximal end of the nail extraction plate.

[0008] Preferably, the distal end of the nail extraction plate has a slope surface, which is located on the side of the nail extraction plate close to the pressing plate, and the slope surface inclines towards the side of the nail extraction plate away from the pressing plate.

[0009] Preferably, the length of the nail extraction plate is greater than the length of the pressing plate.

[0010] Preferably, the distal end of the nail extraction head rod is bent.

[0011] Preferably, the staple remover with a fixing function further includes a fixing head rod disposed at the other end of the handle, and an adjusting portion is provided at the distal end of the fixing head rod.

[0012] Preferably, the adjusting portion is conical, and the tip of the cone of the adjusting portion faces away from the proximal end of the fixing head rod.

[0013] Preferably, the handle includes an upper section, a middle section, and a lower section that are sequentially connected. The staple removing head rod is disposed on the upper section, the fixing head rod is disposed on the lower section, and knurled patterns are provided on the surfaces of the upper section and the lower section.

[0014] Preferably, the staple remover with a fixing function is made of medical stainless steel.

[0015] The above solution of the present utility model has the following beneficial effects:

[0016] In this application, by arranging the staple removing plate and the pressing plate at intervals, the staple cap of the film nail is clamped by the pressing plate and the staple removing plate. Therefore, during the process of removing the staple, the film nail is restricted by the obstruction of the pressing plate and will not fly out, which is safer.

[0017] Other features and advantages of the present utility model will be described in detail in the subsequent specific implementation section. Description of the Drawings

[0027] To make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] As Figures 1-4 shown, an embodiment of the present utility model provides a staple remover with a fixing function, including a handle. At one end of the handle, a staple removal head rod 20 is provided. The proximal end of the staple removal head rod 20 is fixed to the handle, and a pressing plate 21 and a staple removal plate 23 are provided at the distal end of the staple removal head rod 20. The pressing plate 21 and the staple removal plate 23 are spaced apart, and the spacing distance is less than or equal to the thickness of the nail cap of the membrane nail M. To clarify the distal end and proximal end of the staple removal plate 23 and the staple removal head rod 20, it is defined that the end of the staple removal plate 23 and the staple removal head rod 20 away from the handle is the distal end, and the end close to the handle is the proximal end. A notch 25 is provided at the distal end of the staple removal plate 23, and the notch 25 extends from the distal end of the staple removal plate 23 towards the proximal end of the staple removal plate 23.

[0029] When using the staple remover of the present application, the nail cap of the membrane nail M is clamped between the pressing plate 21 and the staple removal plate 23. Therefore, when prying the membrane nail M, the pressing plate 21 restricts the membrane nail M, and it can effectively prevent the membrane nail M from detaching from the staple removal plate 23.

[0030] Furthermore, to make it easier for the staple removal plate 23 to be inserted between the membrane nail M and the treatment site, the distal end of the staple removal plate 23 has a slope 27. The slope 27 is located on the side of the staple removal plate 23 close to the pressing plate 21. The slope 27 inclines towards the side of the staple removal plate 23 away from the pressing plate 21 and forms an angle R with the side away from the pressing plate 21, and the angle R is an acute angle.

[0031] Due to the existence of the slope 27, the distal end of the staple removal plate 23 is more easily inserted between the membrane nail M and the treatment site, and the membrane nail M can be better clamped between the pressing plate 21 and the staple removal plate 23 under the guidance of the notch 25 and the slope 27.

[0032] Furthermore, the length of the staple removal plate 23 is greater than the length of the pressing plate 21, so that a height difference is formed at the distal end of the staple removal plate 23, and this height difference helps the membrane nail M to be stuck into the notch 25.

[0033] Furthermore, the distal end of the staple removal head rod 20 is bent to facilitate the formation of a fulcrum when removing the staple.

[0034] The staple remover with a fixing function further includes a fixing head rod 30, and the fixing head rod 30 is provided at the other end of the handle. To clarify the distal end and proximal end of the fixing head rod 30, it is defined that the end of the fixing head rod 30 away from the handle is the distal end, and the end close to the handle is the proximal end. An adjustment part 31 is provided at the distal end of the fixing head rod 30, and the adjustment part 31 can move the biological membrane and temporarily fix the biological membrane. Preferably, the adjustment part 31 is conical, and the tip of the cone of the adjustment part 31 faces the distal end of the fixing head rod 30.

[0035] Preferably, the handle includes an upper section 11, a middle section 13, and a lower section 15 that are connected in sequence. The nail extraction head rod 20 is fixed to the upper section 11, and the fixing head rod 30 is fixed to the lower section 15. Knurled threads are provided on the surfaces of the upper section 11 and the lower section 15 to increase the friction during gripping.

[0036] Preferably, the nail extractor with a fixing function is made of medical stainless steel. Understandably, the fixing head rod 30 and the adjustment portion 31 are also made of medical stainless steel. Since the nail extractor with a fixing function is made of medical stainless steel and has a certain resilience, when the interval between the pressing plate 21 and the nail extraction plate 23 is less than the thickness of the nail cap of the membrane nail M, the nail cap can still be squeezed between the pressing plate 21 and the nail extraction plate 23 to achieve the fixation of the nail cap.

[0037] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
