[0037] This application provides a medical power handle and a medical power device, wherein the medical power device includes a main unit and a medical power handle. The main unit is connected to the medical power handle for controlling the operation of the medical power handle. The medical power handle is used to connect a cutting tool so that, during surgical bone or soft tissue resection, the cutting tool can perform corresponding cutting operations on the diseased bone tissue by high-speed planing, grinding, etc., thereby opening an internal channel for surgical instruments to enter the human tissue to perform surgery.
[0038] The following description uses a medical power device, specifically a joint planer used for planing or grinding soft tissues of joints, as an example, and a medical power handle used in this joint planer to illustrate the structure of the medical power handle provided in this application. It is understood that the medical power handle provided in this application can also be used in any medical device and is not limited to a joint planer handle; therefore, no limitation is made here.
[0039] See Figure 1 and Figure 2 , Figure 1 A schematic diagram of the appearance of a medical power handle according to one embodiment of this application is shown. Figure 2 for Figure 1Figure 1 is a sectional view along the direction of A-A, the medical power handle (hereinafter referred to as handle 10) provided by an embodiment of the present application comprises a handle main body 100 and an electrical element 200, wherein the handle main body 100 has a sealed cavity 101 therein, and the electrical element 200 is arranged in the sealed cavity 101, and the handle main body 100 is used to connect a cutter and drive the cutter to perform a cutting operation such as planing or grinding.
[0040] Specifically, in one embodiment, the handle main body 100 comprises a handle shell 110 and a cable assembly 120, and opposite ends of the handle shell 110 are defined as a proximal end (i.e. the end of the handle 10 close to the operator when the operator holds the handle 10) and a distal end (i.e. the end of the handle 10 away from the operator when the operator holds the handle 10), and the proximal end of the handle shell 110 is provided with a cable mounting opening 102, the cable assembly 120 is arranged in the cable mounting opening 102 and seals the cable mounting opening 102, and the cable assembly 120 and the handle shell 110 form the sealed cavity 101 of the handle main body 100. Meanwhile, the end of the cable assembly 120 inserted into the handle shell 110 is also electrically connected to the electrical element 200, and the end exposed outside the handle shell 110 is used to be connected to a host machine, so that the host machine can supply power to the electrical element 200.
[0041] Please continue to refer to Figure 2 The cable assembly 120 comprises a cable 121 and a cable connecting sleeve 122, one end of the cable 121 extends into the sealed cavity 101 and is electrically connected to the electrical element 200, the cable connecting sleeve 122 is arranged outside the cable 121 and is sealingly connected to the cable 121, and the cable connecting sleeve 122 is inserted into the cable mounting opening 102 and is sealingly connected to the cable mounting opening 102 in a matching manner. The cable 121 is used to connect the host machine and the electrical element 200, so that the host machine can supply power to the electrical element 200 and transmit signals, and the cable connecting sleeve 122 is used to seal the cable mounting opening 102 and fix the cable 121.
[0042] It can be understood that the cable connecting sleeve 122 can be sealingly connected to the cable 121 by interference fit, or by a sealing member such as a sealing ring or a sealing ring, and the cable connecting sleeve 122 can be sealingly connected to the cable mounting opening 102 by interference fit or by a sealing member, which is not limited here.
[0043] As described in the background, after the handle 10 is used, it needs to be steam cleaned and sterilized in a high-temperature, high-pressure and sterilized environment for the next use. However, if the handle 10 is not sealed well when it is shipped, water vapor will continuously penetrate into the handle 10 when it is cleaned and sterilized in a high-temperature steam environment. Over time, the water vapor that penetrates into the handle 10 will damage the electrical components 200 inside the handle 10, causing the electrical components 200 to short circuit or not work properly, thereby affecting the user's experience. The existing medical power handle 10 cannot simulate the external pressure scenario when it is subjected to high-temperature steam sterilization when it is shipped, so the user cannot know the sealing performance status of the handle 10 when it is shipped, resulting in a certain probability of failure due to high-temperature steam sterilization when the handle 10 is used in a hospital.
[0044] Therefore, in order to solve the above problems, as shown in Figure 2 In an optional embodiment, airtightness detection hole 120a is provided on the cable connection sleeve 122 of the cable assembly 120, and the airtightness detection hole 120a communicates the sealed cavity 101 with the external environment. The purpose of providing the airtightness detection hole 120a is to enable the staff to conveniently detect the sealing performance status of the handle 10 when it is shipped, so as to reduce the number of times that the handle 10 is returned to the factory for repair due to poor sealing performance.
[0045] The airtightness detection hole 120a provides an interface for detecting the airtightness of the sealed cavity 101. The specific detection method can be various. For example, the handle 10 can be placed in a pressurized air cylinder, and a hose is connected to one end of the airtightness detection hole 120a. The end of the hose away from the airtightness detection hole 120a is placed in water. If the handle 10 is not sealed well, the air pressure in the sealed cavity 101 will be higher, and at this time the pressure in the sealed cavity 101 will cause the end of the hose placed in the water to produce bubbles. In this way, the external pressure scenario of the handle 10 when it is subjected to steam sterilization can be simulated in all directions, so that the staff can conveniently know the sealing performance status of the handle 10 when it is shipped, thereby reducing the number of times that the handle 10 is returned to the factory for repair due to poor sealing performance, and greatly improving the reliability of the handle 10. Of course, a pressure gauge or a helium mass spectrometer can also be connected to the airtightness detection hole 120a in a high-pressure environment for airtightness detection. Soap solution can also be directly applied to the airtightness detection hole 120a in a high-pressure environment to observe whether bubbles are generated.
[0046] Further, as shown in Figure 3As shown, the handle 10 further comprises a blocking piece 300 which detachably blocks the airtightness detection hole 120a, and is used to block the airtightness detection hole 120a when no detection is performed, so as to maintain the sealing state of the sealed cavity 101 of the handle main body 100, so that the airtightness detection hole 120a is not in communication with the external environment during the daily use of the handle 10; when the sealing detection is needed, the blocking piece 300 is removed for detection, which greatly facilitates the operation of the staff.
[0047] In order to make the blocking piece 300 more reliably block the airtightness detection hole 120a, in some embodiments, as shown, a sealing ring mounting hole 120b is formed on the cable assembly 120, for example, in the embodiment shown in the figure, the sealing ring mounting hole 120b is formed on the cable connecting sleeve 122, and an elastic sealing ring 400 is mounted in the sealing ring mounting hole 120b. The internal passage structure of the elastic sealing ring 400 forms a deformable airtightness detection hole 120a, so that the airtightness detection hole 120a is indirectly formed on the cable assembly 120. Since the elastic sealing ring 400 can be deformed under the action of external force, when the blocking piece 300 is inserted into the airtightness detection hole 120a, the blocking piece 300 pushes the inner wall of the elastic sealing ring 400, so that the outer wall of the elastic sealing ring 400 is in sealing contact with the inner wall of the sealing ring mounting hole 120b, and the inner wall of the elastic sealing ring 400 is in sealing contact with the outer wall of the blocking piece 300. Therefore, by arranging the elastic sealing ring 400, the sealing of the airtightness detection hole 120a by the blocking piece 300 can be enhanced, and the leakage of external air or water vapor into the sealed cavity 101 can be better prevented.
[0048] In an optional embodiment, a limiting piece 500 is further detachably arranged in the sealing ring mounting hole 120b. When the blocking piece 300 is mounted in the airtightness detection hole 120a, the limiting piece 500 is blocked at the end of the blocking piece 300 away from the sealed cavity 101. Optionally, the end of the limiting piece 500 close to the blocking piece 300 abuts against one end face of the elastic sealing ring 400. By arranging the limiting piece 500, the elastic sealing ring 400 can be prevented from being loosened from the end of the sealing ring mounting hole 120b away from the sealed cavity 101, and the blocking piece 300 can also be prevented from being loosened from the end of the airtightness detection hole 120a away from the sealed cavity 101.
[0049] In order to fix the limiting member 500 and prevent it from being detached from the sealing ring mounting hole 120b, the limiting member 500 is threadedly mounted in the sealing ring mounting hole 120b. In this way, the limiting member 500 can be moved along the axial direction of the sealing ring mounting hole 120b by rotating the limiting member 500, so as to facilitate the installation or removal of the limiting member 500 from the sealing ring mounting hole 120b. Of course, the limiting member 500 can also be fixed in the sealing ring mounting hole 120b by interference fit, which is not limited in this regard.
[0050] It is worth noting that when the plugging member 300 is inserted into the air tightness detection hole 120a, the elastic sealing ring 400 will be subjected to a pushing force. In order to prevent the elastic sealing ring 400 from being detached from the sealing ring mounting hole 120b near the sealing cavity 101 due to the pushing force, the sealing ring mounting hole 120b can be a stepped hole, which is provided with a stepped surface. When the plugging member 300 is installed in the air tightness detection hole 120a, the end of the elastic sealing ring 400 near the sealing cavity 101 abuts against the stepped surface. In this way, due to the blocking of the stepped surface, even if the elastic sealing ring 400 is subjected to the pushing force applied by the plugging member 300, the elastic sealing ring 400 can be fixed in the sealing ring mounting hole 120b. Moreover, since the end of the elastic sealing ring 400 near the sealing cavity 101 abuts against the stepped surface, the end of the elastic sealing ring 400 near the sealing cavity 101 can be subjected to the abutting force of the stepped surface, so that the elastic sealing ring 400 can be deformed more greatly, thereby being able to better tightly fit the inner wall of the sealing ring mounting hole 120b.
[0051] It should be noted that in other embodiments, the elastic sealing ring 400 can not be provided, and the air tightness detection hole 120a can be directly formed on the cable connecting sleeve 122 or other parts of the cable assembly 120. It can also be understood that the air tightness detection hole 120a can be directly or indirectly formed on the handle housing 110, which is not limited in the above.
[0052] In addition, as an improvement of the above-mentioned embodiments, please continue to refer to Figure 2 The cable assembly 120 further comprises a sheath 600, which comprises a distal end portion 620 (i.e. the portion of the sheath 600 away from the operator when the operator holds the handle 10) and a proximal end portion 610 (i.e. the portion of the sheath 600 close to the operator when the operator holds the handle 10). The distal end portion 620 is sleeved on the cable connecting sleeve 122, and the proximal end portion 610 covers the portion of the cable 121 exposed outside the cable connecting sleeve 122.
[0053] Preferably, the sheath 600 is also an elastic sleeve, so that the inner wall of the sheath 600 can closely fit the cable connecting sleeve 122 and the cable 121. In this way, the sheath 600 covers the airtight detection hole 120a and the plugging piece 300 inside the sheath 600, and the sheath 600 can also seal the airtight detection hole 120a under the premise that the airtight detection hole 120a is sealed by the elastic sealing ring 400 and the plugging piece 300, thereby forming a double sealing of the airtight detection hole 120a, so that the handle 10 can better seal the airtight detection hole 120a without sealing detection, and thus the handle 10 can better prevent water vapor from entering the sealed cavity 101 when being sterilized by high-temperature steam. Moreover, the sheath 600 can also protect the cable 121 from being bent to cause damage or breakage of the wires in the cable 121.
[0054] Further, the outer wall of the cable connecting sleeve 122 is provided with a limiting protrusion 1221, and the distal end portion 620 of the sheath 600 covers the limiting protrusion 1221. Since the sheath 600 is an elastic sleeve, by providing the limiting protrusion 1221, the cable 121 can better hold the sheath 600, preventing the sheath 600 from falling off the cable connecting sleeve 122.
[0055] It should be noted that in other embodiments, the handle body 100 can also be a whole structure, and the cable mounting port 102 is directly provided on the handle body 100, and the cable 121 is arranged in the cable mounting port 102 and connected to the electrical element 200, which is not limited in the present application.
[0056] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but it should be considered that any combination of the technical features is within the scope of the present application as long as the combination does not exist contradictory.
[0057] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be noted that for those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
