Description

Technical Field

[0001] This utility model belongs to the technical field of periosteal elevators, and specifically relates to a periosteal elevator. Background Technology

[0002] The periosteum is a strong connective tissue membrane covering the surface of bone, except for joints. During patient treatment, the periosteum at the affected area needs to be dissected, usually using a periosteal elevator. Existing elevators are medical devices used for periosteal elevator treatment during patient treatment. The periosteal elevator is easy to adjust in length, making it suitable for periosteal elevator treatment at different locations. At the same time, it is easy to aspirate blood and fluid during periosteal elevator treatment, allowing for clear observation of the dissection, thus improving the convenience of fluid aspiration and the observation effect of periosteal elevator treatment during use.

[0003] Existing periosteal elevators require direct extension to the affected area, with medical personnel holding the elevator and using the cutting blade at the end to cut the periosteal tissue. This cutting process often results in blood and fluid covering the area, hindering drainage and making observation difficult. This reduces the clarity of the periosteal procedure and compromises the ease of drainage and observation effectiveness. Therefore, this invention proposes a new periosteal elevator. Utility Model Content

[0004] The purpose of this invention is to provide a periosteal elevator to solve the problems mentioned in the background art, such as the tendency for blood to cover the area to be dissected during the cutting process, making it difficult to absorb and drain the blood, resulting in unclear observation, reduced clarity of observation during periosteal dissection, and affecting the convenience of fluid aspiration and the observation effect of the dissection process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a periosteal elevator, comprising an elevator body, the elevator body including a main rod, a sliding connecting rod disposed inside the main rod, and an integrally formed peeling cutter at the end of the sliding connecting rod; the elevator body also includes:

[0006] A liquid suction mechanism, comprising a liquid suction component disposed inside a peeling cutter, wherein the bottom end of the liquid suction component is provided with a liquid suction communication component inside a sliding connecting rod, and the bottom end of the liquid suction communication component is provided with a connecting component.

[0007] The length adjustment mechanism includes a rotation adjustment component disposed at the connection between the sliding connecting rod and the main rod, and the end of the rotation adjustment component is provided with a compression fixing component.

[0008] Preferably, the liquid suction assembly includes a connecting groove formed inside the peeling cutter, with liquid suction holes one on both sides of the connecting groove inside the peeling cutter, and liquid suction holes two at both ends of the connecting groove inside the peeling cutter.

[0009] Preferably, the connecting groove and the peeling cutter are an integral structure, and the first and second suction holes are connected to the interior of the connecting groove.

[0010] Preferably, the liquid suction communication assembly includes a liquid suction channel formed at the bottom end of the connecting groove inside the sliding connecting rod, and the liquid suction channel and the interior of the sliding connecting rod are an integral structure.

[0011] Preferably, the connecting assembly includes a connector that is threaded to the bottom of the suction channel, a flexible threaded tube is fixedly installed at the end of the connector, and an installation joint is provided at the bottom end of the flexible threaded tube.

[0012] Preferably, the rotation adjustment assembly includes an externally threaded ring integrally formed on the top of the main rod, and an internally threaded rotating head is rotatably mounted on the outer surface of the externally threaded ring.

[0013] Preferably, the extrusion fixing assembly includes a clamp plate integrally formed on the top of the external threaded ring, and an arc-shaped extrusion surface is injection molded at the inner top edge of the internal threaded rotating head.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a suction mechanism, before the periosteal elevator body is used, the end of the flexible threaded tube can be fixedly installed to the external suction machine via the installation connector. When blood and fluid appear at the affected area during periosteal dissection, the suction machine operates. When blood and fluid appear at the location of the dissection cutter, air is drawn into the connecting groove through suction holes one and two. After entering the connecting groove, the fluid enters the flexible threaded tube again through the suction channel and is discharged to the outside through the installation connector. This facilitates fluid suction during dissection, allowing for clear observation and operation of periosteal dissection, and improving the convenience of fluid suction and the observation effect of periosteal dissection during use.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a periosteal elevator, including a periosteal elevator body 100, the periosteal elevator body 100 including a main rod 101, a sliding connecting rod 102 disposed inside the main rod 101, and a peeling cutter 103 integrally formed at the end of the sliding connecting rod 102. After the periosteal elevator body 100 can be adjusted to the length of use, medical personnel can directly hold the main rod 101 and the sliding connecting rod 102 to contact the peeling cutter 103 with the affected area to perform periosteal peeling. The periosteal elevator body 100 is also provided with:

[0025] The suction mechanism includes a suction component located inside the peeling cutter 103. The bottom end of the suction component is located inside the sliding connecting rod 102 and has a suction communication component. The bottom end of the suction communication component has a connecting component. When the periosteal elevator body 100 is used for peeling and blood appears at the peeling site, the suction mechanism can clearly observe and treat the peeling process, making the suction process more convenient.

[0026] To facilitate the removal of blood and fluid from the detached periosteum using the suction assembly, and to allow for convenient suction and clear observation of the detachment process, in this embodiment, preferably, the suction assembly includes a connecting groove 1036 inside the detachment cutter 103. Suction holes 1031 are formed on both sides of the connecting groove 1036 inside the detachment cutter 103, and suction holes 1032 are formed at both ends of the connecting groove 1036 inside the detachment cutter 103. This allows blood and fluid to be drawn into the connecting groove 1036 through the suction holes 1031 and 1032 during the process, and facilitates subsequent drainage.

[0027] In order to facilitate the absorption and drainage of blood and fluid during periosteal dissection by the peeling cutter 103 through the liquid absorption and communication component, and to allow for clear observation of the dissection operation, in this embodiment, preferably, the liquid absorption and communication component includes a liquid absorption channel 1035 located at the bottom end of the connecting groove 1036 inside the sliding connecting rod 102. The liquid absorption channel 1035 and the interior of the sliding connecting rod 102 are an integral structure, which facilitates the drainage of liquid to the outside through the liquid absorption channel 1035 after absorption, thus facilitating liquid absorption processing.

[0028] To facilitate the installation and suction operation of the bottom end of the suction channel 1035 with an external suction machine via the connecting assembly, in this embodiment, preferably, the connecting assembly includes a connector 1034 threaded to the bottom end of the suction channel 1035, which facilitates the fixed installation of the flexible threaded tube 1037 by the connector 1034, making it convenient for fixed installation and use. The flexible threaded tube 1037 is fixedly installed at the end of the connector 1034, and an installation joint 1033 is provided at the bottom end of the flexible threaded tube 1037, which facilitates the installation of the flexible threaded tube 1037 with the external suction machine via the installation joint 1033, making it convenient for installation and suction operation.

[0029] The length adjustment mechanism includes a rotary adjustment component located at the connection between the sliding connecting rod 102 and the main rod 101. The end of the rotary adjustment component is provided with a compression fixing component. The periosteal elevator body 100 can be used by adjusting the length between the main rod 101 and the sliding connecting rod 102 to the length to be used and fixing it in place, thereby improving the convenience of adjusting the length of the periosteal elevator body 100 during use.

[0030] In order to facilitate the rotational fixing installation of the main rod 101 and the sliding connecting rod 102 after length adjustment by means of the rotational adjustment assembly, in this embodiment, preferably, the rotational adjustment assembly includes an external threaded ring 1023 integrally formed on the top end of the main rod 101, and an internal threaded rotating head 1021 rotating on the outer surface of the external threaded ring 1023, so as to facilitate the rotational fixing operation by rotating the internal threaded rotating head 1021 to the top end of the main rod 101 through the external threaded ring 1023.

[0031] In order to facilitate the compression and fixing of the main rod 101 when rotating the internal thread rotating head 1021, in this embodiment, preferably, the compression and fixing assembly includes a clamping plate 1022 integrally formed on the top of the external thread ring 1023, and an arc-shaped extrusion surface 1024 injection molded at the inner top edge of the internal thread rotating head 1021. After length adjustment, the internal thread rotating head 1021 can be rotated and the arc-shaped extrusion surface 1024 can be used to press the clamping plate 1022 against the surface of the clamping plate 1022, which facilitates the clamping plate 1022 to be pressed against the surface of the sliding connecting rod 102 for clamping and fixing.

[0032] The working principle and usage process of this utility model are as follows: When using this periosteal elevator, medical personnel adjust the length of the periosteal elevator body 100 according to the patient's treatment location. The sliding connecting rod 102 can slide inside the main rod 101 to bring the main rod 101 and the sliding connecting rod 102 to the treatment length. After the length is adjusted, the internal thread rotating head 1021 is rotated on the surface of the external threaded ring 1023. When the internal thread rotating head 1021 rotates, it drives the arc-shaped extrusion surface 1024 to press against the surface of the clamping plate 1022 until the clamping plate 1022 is pressed against the outer surface of the sliding connecting rod 102 and clamped and fixed. Thus, the periosteal peeling is performed at the usable length between the sliding connecting rod 102 and the main rod 101. Medical personnel can then directly hold the main rod 101 and the sliding connecting rod 102 and contact the peeling cutter 103 with the affected area to perform periosteal peeling.

[0033] Before use, the flexible threaded tube 1037 of the periosteal elevator body 100 is fixedly installed to the external suction machine via the mounting connector 1033. When blood appears at the affected area during periosteal peeling by the peeling cutter 103, the external suction machine can be activated. When blood appears at the position of the peeling cutter 103, air is drawn into the connecting groove 1036 through the suction hole 1031 and the suction hole 2 1032. After the liquid enters the connecting groove 1036, it enters the flexible threaded tube 1037 again through the suction channel 1035 until it is discharged to the outside again through the mounting connector 1033. This facilitates the suction treatment during peeling, making the periosteal peeling clear and improving the convenience of suction treatment and the observation effect of periosteal peeling treatment when using the periosteal elevator body 100.

[0034] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
