Description

Technical Field

[0001] The utility model relates to the technical field of periosteal strippers, in particular to a periosteal stripper with scales. Background Art

[0002] The periosteum is a layer of tough connective tissue wrapped around the surface of the bone. The periosteum plays an important role in bone growth, repair and nutrition. It is also a sensory organ of the bone and participates in the perception of bone pain. Periosteal stripping is a common surgical operation used to separate the periosteum from bone tissue or other soft tissues for fracture reduction and fixation, bone transplantation, bone resection and other operations. The periosteal stripper is a special surgical instrument used to strip the periosteum. In ophthalmic surgeries such as orbital fracture repair, a periosteal stripper is often used to strip the orbital periosteum to expose the fracture area or diseased bone tissue for repair, resection and other operations. The orbit is cone-shaped, and the optic nerve and important blood vessels and muscles are all emitted at the orbital apex. Therefore, during the surgical operation, it is necessary to avoid excessive separation of the periosteum into the deep part of the orbit to avoid damaging the important structures of the orbital apex. At the same time, accurate measurement of the range of the lesion or injury site during the operation can also help with precise surgery, selection of appropriate size repair materials, or design of the resection range. Therefore, it is very important to be able to confirm the depth of the instrument entering the orbit and the approximate size of the lesion area at any time during the operation.

[0003] At present, there are many types and specifications of periosteal elevators on the market, but most of them are single-headed or double-headed, with a flat or curved sheet-like structure on the head and a smooth or knurled cylindrical structure or a flat structure on the handle. Although these periosteal elevators can meet general surgical needs, they also have some shortcomings, such as:

[0004] The lack of scales or markings makes it impossible to accurately measure or control the depth and range of the stripping, which increases the risk and difficulty of the operation. Therefore, it is necessary to develop a new type of periosteal stripper to solve the above problems and improve the efficiency and safety of periosteal stripping. Summary of the invention

[0036] The following is combined with Figure 1-Figure 11 The utility model is further described with implementation modes.

[0037] The specific embodiments of the present utility model are:

[0038] Example 1

[0039] A periosteal stripper with scales comprises a handle 1 and a head 6, wherein the end of the handle 1 is provided with the head 6;

[0040] The scale 2 is arranged on one side of the head 6 and extends from the outer end of the head 6 toward the direction close to the handle 1. The scale 2 can be used to conveniently measure the depth according to the length of penetrating into the eye socket or nasal cavity, avoid excessive or insufficient stripping, protect the integrity of the periosteum, and promote bone healing;

[0041] The head 6 is a flat structure.

[0042] One end of the head 6 is connected to the support block 3 through the support rod 5 , and the support block 3 is connected to the end of the handle 1 .

[0043] like Figure 1 As shown, the head 6, support rod 5, support block 3 and handle 1 are an integrally formed structure. By integrally forming the head 6, support rod 5, support block 3 and handle 1, the structural strength and stability of the periosteal stripper can be enhanced, and loosening or falling off during the stripping process can be avoided, thereby improving the safety and reliability of the stripping; at the same time, the manufacturing process of the periosteal stripper can be simplified, the manufacturing cost can be reduced, and the manufacturing efficiency can be improved.

[0044] In this embodiment, the surface of the handle 1 may be provided with a pattern that increases friction, so as to prevent slipping and prevent the handle from slipping out of the hand.

[0045] Example 2

[0046] like Figure 2 and Figure 3As shown, one end of the head 1 is fixedly connected to one end of the support rod 5, the other end of the support rod 5 is fixedly connected to the small end of the conical connecting block 51, the center of the large end of the conical connecting block 51 is fixedly connected to one end of the cross-shaped limiting rod 52, the cross-shaped limiting rod 52 is plugged into the threaded rod 11, one end of the threaded rod 11 is fixedly connected to the end of the handle 1, the threaded rod 11 is threadedly connected to the support block 3, the support block 3 is cylindrical, the support block 3 includes a cylindrical tube 32 and a conical tube 31, the cylindrical tube 32 is threadedly connected to the threaded rod 11, the large end of the cylindrical tube 32 and the conical tube 31 are fixedly connected, the conical connecting block 51 is arranged in the conical tube 31, and the support rod 5 passes through the small end of the conical tube 31.

[0047] A cross-shaped groove 12 is provided in the center of the threaded rod 11 along the central axis. When the cross-shaped limiting rod 52 is fully inserted into the cross-shaped groove 12 and the support block 3 and the threaded rod 11 are threadedly locked, the conical cylinder 31 presses the conical connecting block 51 .

[0048] Specifically, the head 6 and the support block 3 are connected together by passing the support rod 5 fixedly connected to the head 6 through the conical tube 31, so as to realize the detachable connection between the head 6 and the handle 1, and the cross-shaped limiting rod 52 is fully inserted into the cross-shaped groove 12, and the support block 3 and the threaded rod 11 are threadedly locked. At this time, the conical tube 31 presses the conical connecting block 51 to realize the connection between the head 6 and the handle 1. In this way, the threads of the support block 3 and the threaded rod 11 can be loosened, and the cross-shaped limiting rod 52 can be pulled out from the cross-shaped groove 12, and a new head 6 of other specifications can be replaced, so as to facilitate the periosteal stripping of other parts. In this way, one handle 1 can match multiple different heads 6, saving resources.

[0049] Optionally, in some embodiments, the head 6 and the support rod 5 are also detachably connected, so that the head 6 of different sizes and angles can be directly replaced more conveniently to meet different surgical requirements.

[0050] Example 3

[0051] like Figure 4 As shown, the head 6 is a flat structure, and both sides of the head 6 are flat cross-sections.

[0052] Specifically, the end of the head 6 away from the support rod 5 is in a flat arc shape. The flat arc structure can be a linear structure or a curved structure with the end concave to one side. Preferably, the scale 2 is arranged on the side of the head 6 that bulges outward to facilitate observation of the scale.

[0053] By designing the head 6 to be in a flat arc shape, the stripping area and stripping angle of the head 6 can be increased, thereby improving the stripping effect and flexibility and adapting to different periosteum curvatures and shapes.

[0054] The edge of the head is provided with a thin blade 61, which can increase the stripping force and cutting force of the head 6, improve the smoothness and accuracy of the stripping, and also can cut the mucosa, thus realizing a multifunctional periosteal stripper.

[0055] Example 4

[0056] like Figure 5 As shown, heads 6 are respectively provided at both ends of the handle 1. By providing heads 6 of different sizes or shapes at both ends, the use range and flexibility of the periosteal stripper can be increased. According to different surgical requirements, a suitable head 6 can be selected for stripping, thereby improving the efficiency and convenience of stripping. In the present embodiment, the scale 2 on the head 6 starts counting from the outer end of the head 6 toward the direction close to the handle 1 (the unit of measurement can be millimeters or centimeters), and a scale midline is provided at the center of the handle 1. By setting the scale midline, the scales 2 of the heads 6 at both ends can be easily aligned to ensure the symmetry and accuracy of the stripping and avoid deviations and errors in the stripping. The diameter of the handle 1 is slightly larger than the width of the head 6. The handle 1 can be flat or cylindrical. When the handle 1 is cylindrical, symmetrical horizontal walls are provided on the outer peripheral surface of the handle 1, which is convenient for holding, can increase the grip and friction of the handle 1, prevent the handle 1 from sliding in the hand, and improve the feel and operability of the handle 1.

[0057] Example 5

[0058] like Figure 6 As shown, only one end of the handle 1 is provided with a head 6, and the handle 1 is a flat square rod structure, and the other end of the handle 1 is rounded and has a thin blade on the edge, which is convenient for separating the handle end of the handle 1. By designing the handle 1 as a flat square rod structure, the gripping force and friction force of the handle 1 can be increased, and the handle 1 can be prevented from sliding in the hand, thereby improving the feel and operability of the handle 1; by designing the other end of the handle 1 to be rounded and having a thin blade on the edge, the separation force and cutting force of the handle 1 can be increased, and the smoothness and accuracy of the separation can be improved. At the same time, the mucosa can also be cut, thereby realizing a multifunctional periosteal stripper.

[0059] Example 6

[0060] like Figure 7 As shown, the end of the head 6 away from the support rod 5 is flat-headed. By designing the head 6 to be flat-headed, the head 6 can form a right angle with the periosteum, thereby improving the stability and accuracy of the peeling and adapting to different periosteum thicknesses and hardnesses.

[0061] Example 7

[0062] like Figure 8As shown, the handle 1 is provided with a head 6 only at one end, and the handle 1 is cylindrical. This is a single-head stripper that only uses the head 6 to work. By designing the handle 1 to be cylindrical, the handle 1 can be made lighter and simpler, easier to carry and use, and suitable for general periosteal stripping needs; by only providing the head 6 at one end of the handle 1, the production cost and material consumption of the periosteal stripper can be reduced, thereby improving the economy and environmental protection of the periosteal stripper.

[0063] Example 8

[0064] like Fig. 9 As shown, the heads 6 arranged at both ends of the handle 1 have different specifications, which is convenient for operation on different parts and easy to use. According to different bone parts and the thickness of periosteum, a suitable head 6 can be selected for stripping, thereby improving the adaptability and flexibility of stripping.

[0065] Example 9

[0066] like Fig.10 As shown, the handle 1 and the head 6 are both provided with scales 2, and the scale 2 extends from one end of the head 6 toward the direction of the handle 1. In the present embodiment, the head 6 is provided at both ends or one end of the handle 1. When the head 6 is provided at both ends of the handle 1, the scales 2 are provided starting from the outer ends of the heads 6 at both ends, and the scales 2 extend toward the center of the handle 1. The scale midline can be provided in the middle of the handle 1. When the head 6 is provided at one end of the handle 1, the scale 2 extends from one end of the head 6 toward the direction of the other end of the handle 1. The length of the scale 2 can be set as needed. Preferably, the scale 2 extends from one end of the head 6 to the tail of the handle 1. In the present embodiment, the handle 1, the head 6, the support rod 5 and the support block 3 are designed as an integral part.

[0067] Example 10

[0068] like Fig.11 As shown, the head 6 is hollow, the head 6 and the handle 1 are connected to each other, a liquid inlet is provided on the head 6, and an interface is provided on the handle 1, and the interface is used to connect to a negative pressure suction machine. When performing periosteal stripping operation, not only can the depth be measured, but also the negative pressure suction machine can be started to clean up bleeding in time.

[0069] The method of using the utility model is as follows: hold the handle 1 in the hand, move the head 6 close to the periosteum to be peeled, make the scale 2 parallel to the periosteum, and select appropriate scales as the starting point and end point of the peeling according to needs.

[0070] The edge of the head 6 is gently drawn under the periosteum along the direction of the periosteum so that the head 6 forms an acute angle with the periosteum, and then the head 6 is pushed forward along the direction of the scale 2 to peel off the periosteum until the predetermined end point is reached.

[0071] Repeat the above steps until the desired extent of periosteal stripping is completed.

[0072] The utility model has the following advantages:

[0073] By setting a scale 2 on one side of the head 6, the depth and range of the stripping can be conveniently measured or controlled, especially when operating in an area where the surgical field is not fully exposed, to avoid excessive or insufficient stripping and protect the integrity of the periosteum. By measuring the stripping range, it is beneficial to the precise implementation of the surgery and reduce the risk of accidental damage to deep tissues.

[0074] By designing the head 6 as a flat structure, it can adapt to different bone parts and periosteum thicknesses, improve the stripping effect and accuracy, and reduce damage to the periosteum.

[0075] By providing a detachable and replaceable head 6 at the end of the handle 1, heads of different sizes and angles can be conveniently replaced as needed to meet different surgical requirements.

[0076] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
