Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a medical endoscope handle. Background Art

[0002] Endoscopes mainly enter the human body through natural channels or small incisions made during surgery, so that changes in relevant parts can be directly observed. According to their development and imaging structure, they can be roughly divided into three categories: rigid tube endoscopes, optical fiber (hose type) endoscopes and electronic endoscopes. Most of them are composed of a flexible part, a handle, a light source and a set of lenses.

[0003] Most of the existing endoscope hands are fixed by an integrally formed shell. For example, the Chinese patent with publication number CN215272592U, entitled: Endoscope handle, fixes its shell and internal components by a fixing assembly, so as to better protect the hose. However, since the hand sizes of different doctors in different departments are different, when holding the handle of the same specification for use, medical personnel with smaller hands will not be able to accurately wrap the handle, which will cause the handle to deviate due to the problem of arm grip during the endoscope operation, thereby affecting the overall endoscope operation accuracy. Therefore, the present application provides a medical endoscope handle to meet the demand. Utility Model Content

[0004] The purpose of the present application is to provide a medical endoscope handle, which solves the problem in the prior art that the handle size cannot be adjusted and adapted, thereby achieving the purpose of improving the comfort and flexibility of use.

[0009] Preferably, a plurality of protective blocks are fixedly connected to the column, and the protective blocks are concave structures clamped on the peripheral sides of the column, a chamfered groove is opened on the top of the protective block, and the steel cable is slidably connected to the inside of the groove of the protective block through the chamfered groove.

[0010] Preferably, a plurality of telescopic rods are fixedly connected to the side wall of the protection block, and the plurality of telescopic rods are distributed at equal intervals, and the free ends of the telescopic rods are fixedly connected to the side wall of the movable plate.

[0014] 2. In the utility model, by providing an adjustment control member and a layered plate, the layered plate can effectively divide the external space of the adjustment control member into a number of independent chambers, and then allow different steel cables to be independently sleeved inside different chambers, and then control the adjustment control member to rotate the device.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0028] Combine the following Figure 1-5 The embodiment shown describes the technical solution of the utility model:

[0029] It includes a connecting head 1 and a steel cable 10, the bottom end of the connecting head 1 is fixedly connected to a column 2 and a mounting head 3, and the mounting head 3 is slidably connected to a plurality of movable plates 14 via a plurality of adjusting blocks 5, one side of the adjusting block 5 is fixedly connected to a compression spring 6, and the other side of the adjusting block 5 is tensioned with a protective block 11 via a transmission wheel 8, and the free end of the protective block 11 is wound around an adjusting control member 12, and the rotating adjusting control member 12 controls the movement of the movable plate 14 to form a handle diameter size by driving the adjusting block 5.

[0030] During use, the connector 1 can be directly connected to an external device through the threaded structure at the free end of the connector 1. The adjusting control member 12 can be independently rotated according to the specific usage needs of different medical personnel, so that the adjusting control member 12 is rotated under the action of its rotational force, and then the steel cable 10 connected thereto is driven to wrap around the peripheral side of the adjusting control member 12. At this time, due to the winding of the steel cable 10, the size of the steel cable 10 itself connected to the side wall of the adjusting block 5 becomes shorter, so that the rotational winding force can be directly converted into a tensile force, and then the clamping member 9 acts on the adjusting block 5, so that the adjusting block 5 is forced to drive the moving plate 14 to move. When several moving plates 14 move at the same time, their relative positions can be changed. Since several moving plates 14 are distributed in a circle, the diameter of the circle will expand or shrink under the action of the rotational force of the adjusting control member 12, so that it can meet the grip strength requirements of the hands of different medical personnel and improve its overall flexibility of use.

[0031] A plurality of mounting grooves 4 are formed at the bottom of the mounting head 3 , and the adjusting block 5 is slidably connected inside the mounting groove 4 , and the free end of the compression spring 6 is fixedly connected to the side wall of the mounting groove 4 .

[0032] The setting of the mounting groove 4 can effectively limit the moving trajectory of the adjusting block 5, so that the adjusting block 5 can better slide along the mounting groove 4 when subjected to force, thereby avoiding the possibility of deviation during adjustment. At the same time, after its use is over, or when the force on the adjusting block 5 disappears, the setting of the compression spring 6 can better enable the adjusting block 5 to reset itself for its subsequent use.

[0033] The interior of the installation groove 4 is rotatably connected to a transmission wheel 8 through a mounting frame 7, and a plurality of transmission wheels 8 are distributed in a ring with the installation head 3 as the center. A steel cable 10 is tensioned on the top of the transmission wheel 8 through a clamping member 9 and an adjusting control member 12.

[0034] During use, when the steel cable 10 is shortened by force, its tension can effectively drive the transmission wheel 8 to rotate along the mounting frame 7, so that the transmission wheel 8 can better transmit the steel cable 10, avoiding friction between the steel cable and the mounting head 3 during the adjustment of the adjustment block 5, thereby causing damage to the steel cable 10 and affecting its service life.

[0035] The top of the adjustment control member 12 is rotatably inserted into the bottom of the column 2, and a plurality of layered plates 13 are fixedly sleeved on the column 2, the plurality of layered plates 13 divide the adjustment control member 12 into a plurality of cavities, a plurality of steel cables 10 are sequentially sleeved inside different cavities, and the layered plates 13 are used to prevent the steel cables 10 from being entangled with each other during adjustment.

[0036] During use, different steel cables 10 can be wound in order inside the cavity formed by different layered plates 13, and the force can be adjusted synchronously and orderly to avoid the possibility of mutual entanglement during the force period. At the same time, during the adjustment period, the adjustment control member 12 is directly twisted to drive the steel cable 10 connected to it to be subjected to force. At this time, the steel cable 10 will rotate synchronously with the adjustment control member 12, so that the steel cable 10 is wound around the adjustment control member 12 under the action of its force, so that the size of the steel cable 10 between the adjustment control member 12 and the adjustment block 5 will be shortened. At this time, the rotational force of the steel cable 10 can be effectively converted into a pulling force acting on the adjustment block 5, so that the adjustment block 5 can be moved and adjusted under the action of its force, and then the movable plate 14 is controlled and adjusted through the adjustment block 5.

[0037] A plurality of protective blocks 11 are fixedly connected to the column 2, and the protective blocks 11 are concave structures clamped on the peripheral sides of the column 2, a chamfered groove is opened on the top of the protective block 11, and the steel cable 10 is slidably connected inside the groove of the protective block 11 through the chamfered groove.

[0038] During use, the provision of the protective block 11 can effectively limit the moving trajectory of the steel cable 10, so that the steel cable 10 can wrap around the side of the early column 2 during use, avoiding the force of moving between the column 2 and the movable plate 14 and then getting entangled, thereby improving its overall safety in use.

[0039] A plurality of telescopic rods 15 are fixedly connected to the side wall of the protection block 11 , and the plurality of telescopic rods 15 are distributed at equal intervals, and the free ends of the telescopic rods 15 are fixedly connected to the side wall of the moving plate 14 .

[0040] When the movable plate 14 is moved by force, its moving force can effectively act on one end of the telescopic rod 15, so that the telescopic rod 15 will also deform and move under the action of the moving force of the movable plate 14, thereby effectively changing its own size and length. At the same time, the setting of the telescopic rod 15 can also effectively limit the moving trajectory of the movable plate 14, so that the movable plate 14 is more stable during adjustment, and the possibility of deviation of the bottom of the telescopic rod 15 due to lack of supporting force is avoided.

[0041] A rubber sleeve 16 is fixedly connected to the mounting head 3 , and the rubber sleeve 16 wraps around the circumference of the plurality of movable plates 14 .

[0042] During use, the rubber sleeve 16 can effectively wrap the plurality of movable plates 14, thereby making the surface of the circular handle structure formed by the plurality of movable plates 14 smoother, thereby improving the comfort of medical personnel during hand-held use.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
