Abstract
Description
Technical Field
[0001] This utility model relates to the field of oral restoration technology, specifically to a medical crown removal forceps for oral restoration. Background Technology
[0002] Medical crown removal forceps are primarily used to remove dental crowns inside the mouth. During dental restoration, when an old crown needs to be replaced, or when a crown becomes loose, damaged, or has poor marginal fit, crown removal forceps are needed to remove it. For example, after a porcelain crown restoration, if a gap is found between the porcelain crown and the abutment tooth, food debris can easily become trapped, causing gingivitis. In this case, crown removal forceps are needed to remove the porcelain crown and redo the restoration.
[0003] The forceps head is a key component of medical crown removal forceps. The forceps head is generally slender and has a specific shape design to adapt to the removal of different types of crowns. Some crown removal forceps have a beak-like shape. Currently, crown removal is done using crown removers. If the crown is too tightly attached, it is necessary to grind the crown in half to break it apart. Breaking apart will inevitably damage the crown and make it impossible to remove it completely. Furthermore, current crown removal forceps with a single crown removal head can only hook onto one side of the crown, making the crown removal process quite cumbersome. Therefore, this device provides a medical crown removal forceps for oral restoration. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a medical crown removal forceps for dental restoration, thereby solving the aforementioned technical problems.
[0005] The present invention adopts the following technical solution: a crown removal forceps for removing crowns from a patient's oral cavity, the crown removal forceps including an operating handle, a connecting cylinder and a crown removal head, the connecting cylinder and the operating handle being threadedly connected, the crown removal head including a first crown removal head and a second crown removal head, the first crown removal head being located at the center of the bottom of the connecting cylinder, the connecting cylinder being provided with an adjustment groove, the upper end of the second crown removal head passing through the adjustment groove and located inside the connecting cylinder, the second crown removal head and the adjustment groove being slidably fitted, and a fixing knob being threadedly connected to the upper end of the second crown removal head.
[0006] Furthermore, the first crown removal head is threadedly connected to the center of the bottom of the connecting cylinder.
[0007] Furthermore, the initial state of the first and second crown removal heads is that the sharp parts of the first and second crown removal heads are in close contact.
[0008] Furthermore, by tightening the fixing knob at the upper end of the second crown remover, the second crown remover and the connecting cylinder can be fixed in a limited position and the position can be adjusted.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0027] This utility model provides a medical crown removal forceps for dental restoration, including a crown removal forceps 1 for removing crowns from a patient's oral cavity. The crown removal forceps 1 includes an operating handle 11, a connecting cylinder 12, and a crown removal head 13. The connecting cylinder 12 is threadedly connected to the operating handle 11. The crown removal head 13 includes a first crown removal head 14 and a second crown removal head 15. The first crown removal head 14 is located at the center of the bottom of the connecting cylinder 12. The connecting cylinder 12 is provided with an adjustment groove 16. The upper end of the second crown removal head 15 passes through the adjustment groove 16 and is located inside the connecting cylinder 12. The second crown removal head 15 and the adjustment groove 16 are slidably fitted. A fixing knob 18 is threadedly connected to the upper end of the second crown removal head 15.
[0028] When a patient's crown needs to be replaced, or if the crown is loose, damaged, or has poor marginal fit, this device allows a medical professional to remove it by holding the operating handle 11 and hooking the crown removal head 13 onto the crown. The crown removal head 13 serves as both a first crown removal head 14 and a second crown removal head 15, increasing the contact area between the head 13 and the hook on the crown, thus making it easier for the medical professional to remove the crown. The position of the second crown removal head 15 can be adjusted to fit the curvature of the patient's crown before removal by hooking the crown with the first and second crown removal heads 14 and 15. This method of removing the crown by hooking it at two points is more convenient, less strenuous, and easier to operate.
[0029] This device can remove the patient's crown using only the first crown removal head 14, or by using the first crown removal head 14 and the second crown removal head 15, depending on the tightness of the crown and the treatment process. It is widely adaptable to different patient groups and is more conducive to the removal of crowns.
[0030] In a further preferred embodiment of the present invention, the first crown removal head 14 and the center position of the bottom of the connecting cylinder 12 are connected by a thread;
[0031] The first crown removal head 14 is threadedly connected to the center of the bottom of the connecting cylinder 12, allowing the first crown removal head 14 to be disassembled and replaced with different crown removal heads 13 to provide patients with different methods of crown removal.
[0032] In a further preferred embodiment of the present invention, the initial state of the first crown remover 14 and the second crown remover 15 is that the sharp parts of the first crown remover 14 and the second crown remover 15 are in a close contact state.
[0033] The initial state of the first crown removal head 14 and the second crown removal head 15 is such that the sharp parts of the first crown removal head 14 and the second crown removal head 15 are in close contact, which is conducive to hooking the crown to be removed. After hooking, the contact range is increased, making it easier for medical staff to remove the crown with force.
[0034] In a further preferred embodiment of this utility model, tightening the fixing knob 18 at the upper end of the second crown removal head 15 can limit and fix the second crown removal head 15 and adjust the loosening position of the connecting cylinder 12.
[0035] When the second crown removal head 15 is released from contact with the connecting cylinder 12 after rotating the fixing knob 18, the second crown removal head 15 can be slidably adjusted. According to the curvature of the patient's crown, the second crown removal head 15 can be adjusted to match the first crown removal head 14 and the curvature of the patient's crown. Thus, the crown can be removed by hooking the two points of the patient's crown with the first crown removal head 14 and the second crown removal head 15.
[0036] In a further preferred embodiment of the present invention, the operating handle 11 is provided with a protective thread 17;
[0037] The protective threads 17 on the operating handle 11 can prevent medical staff from slipping their hands during operation and affecting the treatment process.
[0038] In a further preferred embodiment of the present invention, the inclination angle of the sharp crown removal points of the first crown removal head 14 and the second crown removal head 15 is between ten and thirty degrees.
[0039] The sharp tips of the first crown removal head 14 and the second crown removal head 15 are tilted at an angle between 10 and 30 degrees. This angle is designed to comprehensively consider the convenience and safety of oral operations. When removing crowns inside the mouth, the operating space is limited, and the position and shape of the teeth and crowns are relatively complex. A tilt angle of 10 to 30 degrees makes it easier for the sharp tips of the crown removal forceps 1 to insert into the gap between the crown and the abutment tooth. For example, for porcelain crowns, this angle helps to accurately fit the forceps tips along the edge of the crown, find a suitable point of force, and thus make it easier for the dentist to apply force to pry the crown.
[0040] In a further preferred embodiment of this utility model, the length of the crown-removing pliers 1 is between 14 and 22 cm, and the length of the operating handle 11 is between 10 and 16 cm;
[0041] The crown removal forceps 1 is 14-22 cm long, a length range that effectively balances the convenience of oral manipulation and the surgeon's operation. The handle 11 is 10-16 cm long, providing sufficient space for the surgeon's hand to operate outside the mouth, facilitating the application of force, especially when removing firmly attached crowns. The longer handle allows for better leverage. This length is also ergonomic, reducing hand fatigue.
[0042] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this 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 principle of this utility model should be included within the scope of the claims of this utility model.
