Technical Field

[0001] The embodiment of the utility model relates to the technical field of medical instruments, and in particular to a blade clamp. Background Art

[0002] A pathological tissue slicer is a medical device that cuts tissue into slices for pathological diagnosis. It can achieve rapid diagnosis in the field of pathological diagnosis. Tissue slicing can be achieved by clamping a support with tissue on the slicer holder. The slicing device is mainly composed of a blade, a blade holder and a blade holder base.

[0003] The traditional blade clamp mainly locks three nuts through the shaft. The structure of this blade clamp is relatively complex, and the stability of this blade clamp is difficult to ensure during use. Stability is extremely important in pathological diagnosis and may lead to erroneous diagnostic results. Therefore, there is currently a lack of a blade clamp with strong stability and simple structure. Utility Model Content

[0004] To this end, an embodiment of the utility model provides a blade clamp to solve the problem of poor stability in the prior art because the traditional blade clamp mainly locks three nuts through a shaft.

[0005] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0006] According to a blade clamp provided by an embodiment of the utility model, the blade clamp comprises a base body, a cover plate and a blade, one side of the base body is provided with an inclined surface, the inclined surface is provided with a slide rail arranged transversely along the inclined surface, the cover plate is provided with a slider facing the side of the inclined surface, the slide rail matches the slider, the base body and the cover plate are slidably connected through the slide rail and the slider for clamping the blade; the inclined surface is provided with a longitudinal hole, the longitudinal hole is located below the slide rail, the side of the base body is provided with a transverse hole connected to the longitudinal hole, the inner wall of the transverse hole is plugged with a rotating shaft, the rotating shaft is fixedly connected with an eccentric shaft corresponding to the longitudinal hole, the inner wall of the longitudinal hole is plugged with a cylindrical block, the middle part of the cylindrical block is provided with a circular hole, the inner wall of the circular hole away from the inclined surface is fixedly connected with a protruding block, the eccentric shaft is penetrated into the circular hole, and the outer wall of the eccentric shaft slides in fit with the inner wall of the circular hole and the protruding block.

[0007] Furthermore, a handle is fixedly connected to the outer end of the rotating shaft.

[0008] Furthermore, the handle and the rotating shaft are fixedly connected via threads.

[0009] Furthermore, the baffles are rotatably connected to both sides of the cover plate, and a rotatable connection device is provided between the baffles and the cover plate.

[0010] Furthermore, the baffle can rotate along the cover plate, and when the baffle is at the upper end of the blade, the uppermost end of the baffle is higher than the uppermost end of the blade.

[0011] The utility model embodiment has the following advantages:

[0012] The blade clamp provided by the utility model has a base body and a cover plate slidably connected by a slide rail and a slider for clamping the blade, and the slide rail matches the slider. Compared with the traditional method of locking three nuts through an axis, this method has a higher fit between the base body and the cover plate and has strong stability during use; the rotating shaft drives the eccentric shaft, and the eccentric shaft will squeeze the raised block during rotation, at which time the cylindrical block is pressed down, and when it rotates again, it will squeeze the hole wall of the circular hole and push the cylindrical block upward, thereby driving the cylindrical block to move upward to resist the cover plate, and finally achieving the clamping of the blade.

[0022] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1

[0024] The present embodiment provides a blade clamp, including a base 1, a cover plate 2 and a blade 6. A slope is provided on one side of the base 1, and a slide rail 7 is provided on the slope transversely arranged along the slope. A slider 10 is provided on the side of the cover plate 2 facing the slope, and the slide rail 7 matches the slider 10. The base 1 and the cover plate 2 are slidably connected through the slide rail 7 and the slider 10 for clamping the blade 6; a longitudinal hole 9 is provided on the slope, and the longitudinal hole 9 is located below the slide rail 7. A side of the base 1 is provided with a slide rail connected to the longitudinal hole 9. A transverse through hole 8 is provided, and a rotating shaft 4 is inserted into the inner wall of the transverse through hole 8. An eccentric shaft 12 corresponding to the longitudinal hole 9 is fixedly connected to the rotating shaft 4. A cylindrical block 13 is inserted into the inner wall of the longitudinal hole 9. A circular hole 14 is opened in the middle of the cylindrical block 13. A protruding block 15 is fixedly connected to the inner wall of the circular hole 14 away from the inclined surface. The eccentric shaft 12 is inserted into the circular hole 14, and the outer wall of the eccentric shaft 12 is slidably fitted with the inner wall of the circular hole 14 and the protruding block 15.

[0025] The base 1 and the cover plate 2 are slidably connected through the slide rail 7 and the slider 10. The slide rail 7 matches the slider 10, and the base 1 and the cover plate 2 have a higher fit and greater stability during use. The rotating shaft 4 drives the eccentric shaft 12, and the eccentric shaft 12 will squeeze the protruding block 15 during rotation. At this time, the cylindrical block 13 is pressed down, and then the hole wall of the circular hole 14 is squeezed to push the cylindrical block 13 upward, thereby driving the cylindrical block 13 to move upward to resist the cover plate 2, and finally achieving the clamping of the blade 6.

[0026] In this embodiment, a handle 5 is fixedly connected to the outer end of the rotating shaft 4 to facilitate the rotation of the rotating shaft 4 .

[0027] In this embodiment, the handle 5 and the rotating shaft 4 are fixedly connected by threads, so that the handle 5 can be disassembled more conveniently.

[0028] In this embodiment, the number of the longitudinal holes 9 is more than three, and more than three longitudinal holes 9 correspond to the same number of cylindrical blocks 13. The cover plate 2 is supported by multiple cylindrical blocks, so that the base 1 and the cover plate 2 can clamp the blade 6 more firmly.

[0029] In this embodiment, a rotating connection device 11 is arranged between the baffle 3 rotatably connected to both sides of the cover plate 2, and the rotating connection device 11 is a bolt and screw hole structure. Screw holes are arranged on the cover plate 2, and through holes are arranged on the baffle 3. The cover plate 2 and the baffle 3 are connected by bolts, which can make the disassembly of the baffle 3 and the cover plate 2 more convenient.

[0030] In this embodiment, the baffle 3 can rotate along the cover plate 2. When the baffle 3 is at the upper end of the blade 6, the uppermost end of the baffle 3 is higher than the uppermost end of the blade 6. When not in work, the baffle 3 is rotated to the upper end of the blade 6. This can prevent the blade from being exposed to the outside and reduce the risk of injury to the staff.

[0031] In this embodiment, wide and narrow blades can be used interchangeably, and a spacer can be added when a narrow blade is used.

[0032] The principle of this utility model: Figure 3 , 4 As shown in FIG. 1 , when not in operation, the blade holder can be disassembled into a base body 1 and a cover plate 2; when in operation, Figure 2 As shown, the handle 5 is rotated to the lowest position, and the eccentric shaft 12 is driven by the rotating shaft 4 to squeeze the protruding block 15, so that the cylindrical block 13 is driven to move downward along the longitudinal hole 9 until the upper surface of the cylindrical block 13 is parallel to the inclined surface of the base 1, and the base 1 and the cover plate 2 are slidably connected to the appropriate position through the slide rail 7 and the slider 10, and the blade 6 is clamped between the base 1 and the cover plate 2. At this time, by rotating the handle 5 to the highest position, the rotating shaft 4 and the eccentric shaft 12 are driven, and the eccentric shaft 12 drives the upper wall of the circular hole 14, so that the cylindrical block 13 is driven by the eccentric shaft 12 to move upward along the longitudinal hole 9, and finally abuts against the cover plate 2, thereby clamping the blade.

[0033] The cover plate 2 is connected to a baffle 3 via a rotating connection device 11. When not in operation, Figure 1 , 2 As shown, the cover plate 2 rotates to press on the blade 6, and the uppermost end of the cover plate 2 is higher than the uppermost end of the blade 6, playing a protective role.

[0034] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
