Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to an endoscope operating handle. Background Art

[0002] As a commonly used monitoring and diagnostic medical device, endoscopes generally consist of endoscope consumables and endoscope host. Endoscope consumables include a front end, a bending part, an insertion part, and a control part. At present, all endoscopes on the market are reusable endoscopes. Since they need to be reused, in order to avoid cross infection between patients, each endoscope must undergo a strict and complex disinfection procedure after use. According to the relevant disinfection technical operation specifications issued by the Ministry of Health, an endoscope needs to go through 6 to 10 steps of cleaning and disinfection after use, which takes at least 20 minutes. Most of the materials are metal parts or other high-temperature resistant plastic parts, and their production cost is relatively high.

[0003] Therefore, it is necessary to develop a disposable hose electronic medical endoscope, replace the disposable parts at the contact part between the hose endoscope and the human body, and provide a convenient, cheap and safe tool for screening and diagnosis of digestive system diseases. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in order to solve the problem that an endoscope needs to go through 6 to 10 steps of cleaning and disinfection after use, which takes at least 20 minutes, and most of its materials are metal parts or other high-temperature resistant plastic parts, and its production cost is relatively high, an endoscope operating handle is now provided.

[0005] The technical solution adopted by the present invention to solve the technical problem is: an endoscope operating handle,

[0006] It comprises a probe and a handle body, wherein the handle body comprises:

[0007] A lower seat body, on which a probe for observation is arranged;

[0008] A lower connector, which is disposed on the lower seat body and one end of which is connected to the probe;

[0009] an upper seat body, which is opposite to the lower seat body;

[0010] And an upper joint, which is arranged on the upper seat body, and one end of which is connected to an external controller, and the other end of which can be docked with the lower joint. When the upper seat body and the lower seat body are opposite to each other, the upper joint and the lower joint correspond to each other and are staggered. The upper seat body is controlled to rotate in a circular direction relative to the lower seat body, so that the upper joint and the lower joint are docked, thereby realizing that the external control mechanism controls the deflection angle of the probe through the upper joint and the lower joint.

[0011] The present invention places the upper seat body and the lower seat body opposite to each other and docks the upper joint on the upper seat body with the lower joint on the lower seat body, so that the external control mechanism controls the swing angle of the probe through the upper joint and the lower joint. When disassembling, the docked upper joint and lower joint are separated to separate the upper seat body and the lower seat body.

[0012] In order to ensure that the displacement of the lower joint on the lower seat body is stable and reliable, further, one end of the lower seat body is provided with a first slideway matching the lower joint along its axial direction, and the lower joint is slidably arranged in the first slideway. By providing the first slideway matching the lower joint on the lower seat body, the lower joint is restricted, ensuring that the displacement of the lower joint on the lower seat body is stable and reliable.

[0013] In order to prevent the lower joint from rotating, which causes the lower joint and the upper joint to be offset and unable to dock, further, a first limit block is provided on the lower joint along its displacement direction, and a first limit groove matching the first limit block is provided on the inner peripheral wall of the first slideway, and the first limit block is slidably arranged in the first limit groove. By providing the first limit block on the lower joint and cooperating with the first limit groove in the first slideway, the displacement path of the lower joint is limited, and the phenomenon of the lower joint rotating is effectively prevented.

[0014] Since the upper joint and the lower joint are axially displaced between the lower seat body or the upper seat body under the control of an external controller, the lower joint will be located in the first limit groove. In order to restore the lower joint to the initial position, thereby facilitating the separation of the upper joint and the lower joint, a slip ring is further slidably arranged on the lower seat body, and the slip ring contacts the lower joint and can drive the lower joint to displace on the lower seat body, thereby realizing the restoration of the lower joint to the initial position. The slip ring in contact with the lower joint is slidably arranged on the lower seat body, and the slip ring pushes the lower joint to rise and return to the initial position, so that the upper joint and the lower joint can be separated smoothly.

[0015] In order to enable the slip ring to slide on the lower seat body, further, a guide groove is provided on the lower seat body along its axial direction, and a guide block matching the guide groove is provided on the slip ring, and the guide block is slidably arranged in the guide groove. By matching the guide block provided on the slip ring with the guide groove on the lower seat body, the slip ring can slide on the lower seat body, and the structure is simple.

[0016] In order to facilitate the operation of the slip ring, the guide groove further comprises a displacement section, a guide section and a limit section which are sequentially arranged from the lower seat body to the upper seat body, the displacement section is a plane arranged along the axial direction of the lower seat body, the guide section is an inclined surface which is gradually inclined inward from the lower seat body to the upper seat body, the limit section is a plane arranged along the axial direction of the lower seat body, and a limit shoulder for limiting the displacement of the guide block is arranged between the guide section and the limit section.

[0017] In order to ensure that the displacement of the upper joint on the upper seat body is stable and reliable, further, one end of the upper seat body is provided with a second slideway matching the upper joint along its axial direction, the upper joint is slidably arranged in the second slideway, a second limit block is provided on the upper joint along its displacement direction, a second limit groove matching the second limit block is provided on the inner peripheral wall of the second slideway, and the second limit block is slidably arranged in the second limit groove. By providing the second slideway matching the upper joint on the upper seat body, the upper joint is restricted, ensuring that the displacement of the upper joint on the upper seat body is stable and reliable.

[0018] Furthermore, a spring is sleeved on the upper joint, and the spring is located between the second slideway and the upper joint. The spring is used to reset the upper joint to ensure that the upper joint can be docked stably and reliably.

[0019] In order to fix the lower seat body and the upper seat body, further, a fixing groove is provided on the lower seat body, and a fixing pin matching the fixing groove is provided on the upper seat body. The fixing groove includes a sliding section and a fixing section. The fixing section is provided along the radial direction of the lower seat body, and the sliding section is provided along the axial direction of the lower seat body. One end of the sliding section is provided on the fixing section, and the other end of the sliding section passes through an end of the lower seat body close to the lower joint. The fixing pin passes through the sliding section of the fixing groove and is provided in the fixing section. The fixing pin on the upper seat body passes through the fixing groove of the lower seat body, and the fixing pin is located in the fixing section, so as to achieve the fixation between the lower seat body and the upper seat body.

[0020] In order to ensure that the upper joint and the lower joint are connected stably and reliably, further, a clamping block is provided on the lower joint, and the clamping block has an upper end and a lower end arranged in sequence along the axial direction of the lower seat body, the cross-sectional area of ​​the upper end is larger than the cross-sectional area of ​​the lower end, and the lower end is located between the lower joint and the upper end, and a clamping groove matching the clamping block is provided on the upper joint, and the clamping block is clamped in the clamping groove. The clamping block cooperates with the clamping groove, and the cross-sectional area of ​​the upper end of the clamping block is larger than the cross-sectional area of ​​the lower end, which well limits the displacement of the clamping block along the axial direction of the lower joint.

[0021] The beneficial effects of the present invention are: when the endoscope operating handle of the present invention is in use, the upper seat body and the lower seat body are placed opposite each other, and the upper joint on the upper seat body is connected with the lower joint on the lower seat body, so that the external control mechanism controls the swing angle of the probe through the upper joint and the lower joint. When disassembling, the upper seat body and the lower seat body can be separated by separating the connected upper joint and the lower joint, thereby avoiding the need for an endoscope to undergo 6 to 10 steps of cleaning and disinfection after use, which takes at least 20 minutes. Most of the materials selected are metal parts or other high-temperature resistant plastic parts, and the production cost is relatively high. BRIEF DESCRIPTION OF THE DRAWINGS
