Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an oral surgery stripper. Background Art

[0002] At present, there are various kinds of dissipators and auxiliary instruments for oral surgery, which can basically meet the needs of periosteal dissection in various oral surgeries, such as vascular forceps, conventional dissipators, and aspirators mainly used in periosteal dissection.

[0003] Since the structure of the stripping surgical instrument is relatively simple, it has caused many inconveniences in clinical use, resulting in limitations in surgical operations. For example, during the periosteal stripping process, bleeding from the mucoperiosteum and the nutrient bone holes on the bone surface often makes it impossible for the surgeon to clearly see the boundary between the periosteum and the bone surface. An assistant other than the surgeon is required to use a vacuum suction device to keep the surgical field clear. However, during general anesthesia surgery, due to the limitations of the oral space, assistants are often unable to look directly at the surgical area and cannot make good use of the suction device to keep the surgical field clear, thereby slowing down the surgical efficiency and increasing the duration of the operation.

[0004] Therefore, it is necessary to provide an oral surgery stripper to solve the problem in the prior art that bleeding cannot be sucked during the periosteal stripping process, resulting in unclear surgical field. Utility Model Content

[0005] The purpose of the utility model is to provide an oral surgery stripper to solve the technical problems mentioned in the above background technology.

[0006] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0007] The utility model provides an oral surgery stripper, comprising: a handle; a connecting rod, wherein the two ends of the handle are respectively provided with connecting rods; the connecting rods are bent at an obtuse angle and are arranged symmetrically with respect to the center of the handle; a stripping head is fixedly arranged at the end of at least one connecting rod; wherein the inner part of the handle is hollow to form a drainage cavity, one of the connecting rods is provided with a drainage hole passing through along its path to form a drainage rod, and the drainage hole and the stripping head are located close to each other; the drainage rod is connected to the drainage cavity through the drainage hole; a capsule body is arranged around the outer side of the drainage cavity, and a negative pressure hole is arranged on the drainage cavity and surrounded by the capsule body, so that the drainage rod, the drainage cavity, and each chamber in the capsule body are connected to each other.

[0008] Furthermore, the negative pressure hole and the capsule are staggered along the axis direction of the handle;

[0009] Among them, the negative pressure hole is away from the drainage rod along the axial direction of the handle, and the capsule is close to the drainage rod along the axial direction of the handle, so that when the axis of the handle is along the direction of gravity, the negative pressure hole is located at the inner top of the capsule, so that the interior of the drainage cavity is located below the negative pressure hole to form a fluid storage space.

[0010] Furthermore, the inner bottom of the drainage cavity is in an upwardly convex conical shape, and the drainage hole is connected to the middle of the drainage cavity, so that the fluid entering the drainage cavity through the drainage hole is dispersed and guided to the inner wall close to the drainage cavity.

[0011] Furthermore, the connecting rod and the end of the handle are threadedly connected.

[0012] Furthermore, a plurality of drainage holes are arranged on the drainage rod at equal intervals around the axis thereof.

[0013] Furthermore, a drainage groove is provided on one side surface of the stripping head, and the notch of the drainage groove is close to the position of the drainage hole.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model can attract and guide the bleeding caused by the separation of the periosteum in oral surgery into the drainage cavity through the drainage hole by the negative pressure suction effect generated when the capsule is squeezed to make it rebound, so as to avoid the bleeding of the mucoperiosteum and the nutrient bone holes on the bone surface during the stripping process, which makes it impossible for the surgeon to clearly see the boundary line between the periosteum and the bone surface, and avoids the need for assistants other than the surgeon to use vacuum suction equipment to clean up the bleeding during the separation of the periosteum, thus keeping the surgical field clear, improving the surgical efficiency and shortening the operation time.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, the utility model provides an oral surgery peeling device, comprising:

[0027] Handle 1;

[0028] A connecting rod 2 is provided at each end of the handle 1; the connecting rod 2 is bent at an obtuse angle and is centrally symmetrically arranged with respect to the handle 1; a stripping head 21 is fixedly provided at the end of at least one connecting rod 2;

[0029] Among them, the inner part of the handle 1 is hollow to form a drainage cavity 11, and a drainage hole 22 is provided on one of the connecting rods 2 along its path to form a drainage rod 23, and the drainage hole 22 and the stripping head 21 are located close to each other; the drainage rod 23 is connected to the drainage cavity 11 through the drainage hole 22; the outer ring of the drainage cavity 11 is provided with a capsule 12, and the drainage cavity 11 is provided with a negative pressure hole 111 surrounded by the capsule 12, so that the drainage rod 23, the drainage cavity 11, and the various chambers in the capsule 12 are connected to each other.

[0030] The utility model aims to attract and guide the bleeding caused by periosteal separation during oral surgery into the drainage cavity 11 through the drainage hole 22 by the negative pressure suction effect generated when squeezing the capsule 12 to make it rebound, so as to avoid the bleeding of the mucoperiosteum and the bleeding of the nutrient bone holes on the bone surface during the stripping process, which causes the surgeon to be unable to clearly see the boundary between the periosteum and the bone surface, and avoid the need for assistants other than the surgeon to use vacuum suction equipment to clean up the bleeding during periosteal separation, so as to keep the surgical field clear, improve the surgical efficiency, and shorten the surgical time. Specifically, during the operation, when the surgeon performs periosteal separation operation on the patient's oral cavity, the inlet end of the drainage hole 22 may be submerged by the blood and water accumulated in the oral cavity. The surgeon squeezes the capsule 12 to generate negative pressure inside it, so as to use the drainage rod 23 to suck the blood and water up into the drainage cavity 11, so as to clean up the bleeding in the patient's oral cavity, so as to keep the surgical field clear and improve the surgical efficiency.

[0031] In the above embodiment, the diameter of the handle 1 is generally small, that is, the internal capacity of the drainage chamber 11 is small, and when the negative pressure hole 111 is located at the bottom of the drainage chamber 11, since both sides of the negative pressure hole 111 are fluid, this will cause the internal storage space of the drainage chamber 11 to be further limited, making it difficult to store more blood and water entering therein. The blood and water stored in the drainage chamber 11 may easily enter the capsule 12 or return to the patient's mouth due to multiple squeezing of the capsule 12, which is not conducive to the formation of negative pressure in the capsule 12, nor is it conducive to the suction effect of the drainage hole 22 on the blood and water in the patient's mouth.

[0032] In order to solve the above problems, Figure 2 As shown, in the preferred embodiment provided by the present invention based on the above embodiment, the negative pressure hole 111 and the capsule 12 are staggered along the axial direction of the handle 1;

[0033] Among them, the negative pressure hole 111 is away from the drainage rod 23 along the axial direction of the handle 1, and the capsule 12 is close to the drainage rod 23 along the axial direction of the handle 1, so that when the axis of the handle 1 is along the direction of gravity, the negative pressure hole 111 is located at the inner top of the capsule 12, so that the interior of the drainage cavity 11 is located below the negative pressure hole 111 to form a fluid storage space.

[0034] In the present embodiment, the negative pressure hole 111 is arranged in the upper area of ​​the drainage cavity 11, so that the internal storage space of the drainage cavity 11 is increased, so that the blood and water entering therein can be stored more, and the blood and water stored in the drainage cavity 11 will not enter the capsule 12 or return to the patient's mouth due to multiple squeezing of the capsule 12, which is beneficial to the formation of negative pressure in the capsule 12 and the suction effect of the drainage hole 22 on the blood and water in the patient's mouth, thereby improving the efficiency of the operation.

[0035] In the above embodiment, after the blood and water enter the drainage cavity 11 through the drainage hole 22, since the inner bottom of the drainage cavity 11 is a plane, the blood and water may flow back to the patient's oral cavity along the drainage hole 22 due to the action of gravity, causing unclear surgical field and affecting the operation.

[0036] To solve the above problems, please continue to refer to Figure 2 As shown, in a preferred embodiment provided by the utility model based on the above embodiment, the inner bottom of the drainage chamber 11 is an upwardly convex conical surface, and the drainage hole 22 is connected to the middle part of the drainage chamber 11, so that the fluid entering the drainage chamber 11 through the drainage hole 22 is dispersed and guided to the inner wall close to the drainage chamber 11.

[0037] In this embodiment, by setting the inner bottom of the drainage cavity 11 to be conical, the blood and water entering the drainage cavity 11 can be dispersed and guided to be collected near the inner wall of the drainage cavity 11, thereby preventing the blood and water from flowing back to the patient's oral cavity along the drainage hole 22 due to gravity, making the surgical field clear and improving the surgical efficiency.

[0038] In order to facilitate the installation and disassembly between the stripping head 21 and the handle 1 and to adapt to the corresponding surgical operations on different affected parts of the patient, the utility model generally screws the ends of the connecting rod 2 and the handle 1, so as to facilitate the replacement operation of a variety of different stripping heads 21.

[0039] In order to enable the stripper to attract the blood and water in the patient's oral cavity in different circumferential directions and improve the drainage efficiency of the drainage hole 22 for blood and water, as shown in FIG. Figure 5-6 As shown, in a preferred embodiment of the present invention provided based on the above embodiments, a plurality of drainage holes 22 on the drainage rod 23 are equidistantly arranged around the axis thereof.

[0040] In order to use the stripping head 21 to suck the blood deep in the wound of the patient, the blood is sucked into the drainage hole 22 through the side wall of the stripping head 21. Figure 3 As shown, in a preferred embodiment provided by the utility model based on the above embodiment, a drainage groove 24 is provided on one side of the stripping head 21, and the notch of the drainage groove 24 is close to the position of the drainage hole 22. In this embodiment, by providing the drainage groove 24 on the stripping head 21, it can cooperate with the drainage hole 22 to achieve the purpose of sucking blood and water deep in the patient's wound.

[0041] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
