Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a pathological tissue sectioning knife that facilitates the installation of blades. Background Technology

[0002] Pathological diagnosis is the gold standard in clinical medicine, and the pathology department establishes a pathological diagnosis by biopsiing the patient's diseased tissue. The diseased tissue and organs surgically removed from the patient are sent to the pathology department, where pathologists manually extract samples, selecting characteristic lesion areas to prepare tissue sections. Pathologists then observe these tissue sections under a microscope to confirm the pathological diagnosis. A pathological tissue sectioning scalpel is a tool used to section pathological tissue.

[0003] While current pathological tissue sectioning tools improve the convenience for medical staff in obtaining tissue slides, the inventors have discovered shortcomings in practical use, specifically: Existing pathological tissue sectioning scalpels typically include a handle, a blade clamp connected to the front end of the handle, and a blade that is inserted and fitted into the lower end of the blade clamp. During the blade installation process, medical staff usually operate by hand. Since the blade edge is usually not equipped with a protective structure, the blade edge is prone to cutting the hands of medical staff during the manual blade installation process, thus reducing the safety of medical staff when installing blades.

[0004] Therefore, based on the above shortcomings, there is an urgent need to design a pathological tissue sectioning knife that is easy to install blades, so as to improve the safety of medical staff when changing blades. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings of current pathological tissue sectioning knives in practical use by providing a pathological tissue sectioning knife that facilitates blade installation, thereby improving the safety of medical personnel when installing blades.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A pathological tissue sectioning scalpel for easy mounting of a blade includes a housing and a blade for mounting on the housing, the blade being adapted with a protective element; When the blade is not mounted on the housing, the protective member protects the blade edge; The housing is provided with an unlocking component, which is used to cooperate with the protective component. When the blade is installed on the housing, the unlocking component cooperates with the protective component to release the protective component from the blade.

[0007] As the preferred technical solution of this application, a placement cavity is provided inside the housing, the placement cavity extends through the front and rear of the housing, the area at the front of the housing is the front of the housing, and the area at the rear of the housing is the rear of the housing. During the process of installing the blade on the housing, the blade gradually extends into the placement cavity from the rear of the housing, and the protective member gradually cooperates with the unlocking member. After the blade is mounted on the housing, the blade extends from the head of the housing.

[0008] As the preferred technical solution of this application, the protective member includes two clamping plates and a transition plate. The two clamping plates are connected by the transition plate, and a clamping area is formed between the two clamping plates. The width of the clamping area is h. When the protective member protects the blade, the blade is located in the clamping area, and the two clamping plates clamp the blade. When the unlocking component and the protective component cooperate, the protective component deforms, increasing the distance between the two clamping plates and increasing the width h of the clamping area, thereby releasing the two clamping plates from clamping the blade.

[0009] As the preferred technical solution of this application, the unlocking component includes a first sliding groove, which is arranged along the length direction of the housing. The protective component includes a sliding strip, which is arranged along the length direction of the protective component. The sliding strip is adapted to the first sliding groove. During the process of the blade being gradually installed on the housing, the sliding strip gradually engages with the first sliding groove. The width h corresponding to the area on the protective component that engages with the first sliding groove increases, thereby gradually releasing the clamp from holding the blade.

[0010] As a preferred technical solution of this application, the unlocking component further includes a guide groove located at the tail of the housing, which is used to guide the engagement between the slider and the first slide groove.

[0011] As a preferred technical solution of this application, the unlocking component further includes a first abutting component, which is located on the housing. After the protective component extends into the housing, the first abutting component abuts against the protective component, so that when the blade extends from the head of the housing, the protective component is located inside the housing.

[0012] As the preferred technical solution of this application, the protective component is provided with a second abutment. During the process of the blade separating from the housing, the blade is pulled out from the tail of the housing, and the second abutment abuts against the blade, so that the blade and the protective component move synchronously. After the protective component is released from its engagement with the unlocking component, the protective component gradually recovers its deformation, reducing the width h of the clamping area. The two clamping plates resume clamping the blade, and the protective component resumes protecting the blade edge.

[0013] As the preferred technical solution of this application, the blade is provided with a gripping part, which is used by the operator to grip and, after gripping the gripping part, to extend the blade from the tail of the housing into the placement cavity, or to pull the blade in the placement cavity out from the tail of the housing.

[0014] As the preferred technical solution of this application, the blade is provided with a through hole, and the housing is provided with a knob. The knob is used to pass through the through hole and cooperate with the blade. The knob is slidably disposed on the housing. When the knob slides relative to the housing, the sliding direction is in the same direction as the length direction of the housing. When the knob slides relative to the housing, the knob and the blade move synchronously so that the blade extends out of the housing or retracts into the housing.

[0015] As the preferred technical solution of this application, the housing is provided with a second sliding groove, the length direction of the second sliding groove is in the same direction as the length direction of the housing, the knob cooperates with the second sliding groove, the knob can slide relative to the housing along the length direction of the second sliding groove, the knob includes a knob part and a knob part, and the knob part and the knob part are threadedly detachably connected. When the first knob and the second knob are connected, the first knob rotates relative to the second knob to make the first knob and the second knob cooperate to clamp or release the housing. When the knob part one and the knob part two are separated, the knob part one and the knob part two can be removed from the housing.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In the solution of this application, by setting a protective component, the blade is protected when it is not installed on the housing, thereby preventing the blade from cutting the hands of medical staff when they handle the blade, thus improving the safety of medical staff when handling the blade. By setting an unlocking component on the housing, when the blade is installed on the housing, the unlocking component cooperates with the protective component to release the protection of the blade, thereby facilitating the blade to extend out of the housing for subsequent sectioning of pathological tissue. 2. Furthermore, by setting two clamping plates and a transition plate, a clamping area is formed between the two clamping plates. When the protective component protects the blade, the blade is located in the clamping area, and the two clamping plates clamp the blade, thereby improving the stability of the protective component in protecting the blade. When the unlocking component cooperates with the protective component, the protective component deforms, which increases the distance between the two clamping plates and increases the width h of the clamping area. This allows the clamping plates to release the blade, making it easier for the blade to move relative to the protective component. This facilitates the blade extending from the head of the housing while the protective component is inside the housing, thus making it easier for the blade to slice pathological tissue. 3. Furthermore, by setting a second stop, the blade is pulled out from the tail of the housing during the separation process of the blade from the housing, and the second stop abuts against the blade, so that the blade and the protective member move synchronously. At the same time, after the protective member is released from the engagement with the unlocking member, the protective member gradually restores its deformation, reducing the width h of the clamping area. The two clamps gradually restore their clamping of the blade, so that the protective member restores its protection of the blade edge, and all parts of the blade edge can be protected by the protective member, thereby improving the safety when changing the blade. The second stop is located at the end of the protective member, and the second stop is used to abut against the tail of the blade. 4. Furthermore, by setting up a first knob and a second knob, when the first knob and the second knob are connected, rotating the first knob relative to the second knob allows the first knob and the second knob to cooperate in clamping or releasing the housing. When the first knob and the second knob release the clamping action on the housing, the knob can slide along the length of the second slide groove, thereby driving the blade to move and changing the length of the blade extending out of the housing. Furthermore, by rotating the first knob relative to the second knob, the first knob and the second knob cooperate in clamping the housing, thereby fixing the knob and the blade relative to the housing, thus improving the stability of the blade's state when it extends out of the housing head. At the same time, after the first knob and the second knob are separated, the first knob and the second knob can be removed from the housing, thereby disengaging the knob from the blade and facilitating blade replacement.

[0023] Example 1: This example provides a pathological tissue sectioning blade that is easy to install the blade 2. See [link to example]. Figures 1-7 As shown, it includes a housing 1 and a blade 2, the blade 2 being mounted on the housing 1, and the blade 2 being fitted with a protective member 3; When the blade 2 is not mounted on the housing 1, the protective member 3 protects the cutting edge of the blade 2; The housing 1 is provided with an unlocking component 4, which is used to cooperate with the protective component 3. When the blade 2 is installed on the housing 1, the unlocking component 4 cooperates with the protective component 3 to release the protection of the blade by the protective component 3.

[0024] In this application, by setting a protective component 3, the blade 2 is protected by the protective component 3 when it is not installed on the housing 1, thereby preventing the blade 2 from cutting the hands of medical personnel when they handle the blade 2, thus improving the safety of medical personnel when handling the blade 2. By setting an unlocking component 4 on the housing 1, when the blade 2 is installed on the housing 1, the unlocking component 4 cooperates with the protective component 3 to release the protection of the blade 2 from the housing 1, so that the blade 2 can be extended from the housing 1 for subsequent sectioning of pathological tissue.

[0025] As a preferred embodiment, based on the above method, the housing 1 is further provided with a placement cavity 5, which extends through the beginning and end of the housing 1. The area at the beginning of the housing 1 is the housing head 6, and the area at the end of the housing 1 is the housing tail 7. During the process of installing the blade 2 on the housing 1, the blade 2 gradually extends into the placement cavity 5 from the housing tail 7, and the protective member 3 gradually cooperates with the unlocking member 4. After the blade 2 is mounted on the housing 1, the blade 2 extends out from the head 6 of the housing.

[0026] Furthermore, by providing a placement cavity 5, during the process of installing the blade 2 onto the housing 1, the blade 2 gradually extends into the placement cavity 5 from the tail 7 of the housing. After the blade 2 is installed onto the housing 1, the blade 2 can extend out of the placement cavity 5 from the head 6 of the housing. This improves the convenience of installing the blade 2 onto the housing 1 and the convenience of extending the blade 2 out of the housing 1.

[0027] As a preferred embodiment, based on the above method, the protective member 3 further includes two clamping plates 8 and a transition plate 9. The two clamping plates 8 are connected by the transition plate 9, and a clamping area is formed between the two clamping plates 8. The width of the clamping area is h. When the protective member 3 protects the blade, the blade is located in the clamping area, and the two clamping plates 8 clamp the blade 2. When the unlocking component 4 and the protective component 3 cooperate, the protective component 3 deforms, increasing the distance between the two clamping plates 8 and increasing the width h of the clamping area, thereby releasing the two clamping plates 8 from clamping the blade 2.

[0028] Furthermore, by setting two clamping plates 8 and a transition plate 9, a clamping area is formed between the two clamping plates 8. When the protective member 3 protects the blade, the blade is located in the clamping area, and the two clamping plates 8 clamp the blade 2, thereby improving the stability of the protective member 3 in protecting the blade. When the unlocking member 4 cooperates with the protective member 3, the protective member 3 deforms, which increases the distance between the two clamping plates 8 and increases the width h of the clamping area. This allows the clamping plates 8 to release the clamping of the blade 2, making it easier for the blade 2 to move relative to the protective member 3. This makes it easier for the blade 2 to extend from the head 6 of the housing, with the protective member 3 in the housing 1, and thus easier for the blade 2 to slice pathological tissue.

[0029] As a preferred embodiment, based on the above method, the unlocking component 4 further includes a first sliding groove 10, which is arranged along the length direction of the housing 1. The protective component 3 includes a sliding strip 11, which is arranged along the length direction of the protective component 3. The sliding strip 11 is adapted to the first sliding groove 10. As the blade 2 is gradually installed on the housing 1, the sliding strip 11 gradually engages with the first sliding groove 10. The width h corresponding to the area on the protective component 3 that engages with the first sliding groove 10 increases, so that the clamping plate 8 gradually releases its grip on the blade 2.

[0030] Furthermore, by setting the first slide groove 10 and the slide bar 11, as the blade 2 is gradually installed on the housing 1, the slide bar 11 gradually engages with the first slide groove 10, thereby increasing the width h of the area on the protective member 3 that engages with the first slide groove 10. This causes the clamping plate 8 to gradually release its grip on the blade 2. Thus, when the blade 2 is not fully installed on the housing 1, the part of the blade 2 that does not extend into the placement cavity 5 can still be protected by the protective member 3, further improving the safety when installing the blade 2. At the same time, after the blade 2 is safely installed on the housing 1, the clamping plate 8 releases its grip on the blade 2, making it easier for the blade 2 to extend out of the housing 1 for slicing operations. The protective component 3 can be made of plastic. After the slider 11 is engaged with the first slide groove 10, the protective component 3 deforms, which increases the width h of the area on the protective component 3 that is engaged with the first slide groove 10. After the slider 11 is disengaged from the first slide groove 10, the protective component 3 can restore its deformation, which decreases the corresponding width h.

[0031] Example 2: Based on the technical solution of Example 1, further details are provided below. Figures 1-7 As shown, the unlocking component 4 also includes a guide groove 12, which is located at the tail of the housing 7. The guide groove 12 is used to guide the engagement between the slide bar 11 and the first slide groove 10.

[0032] Furthermore, by setting a guide groove 12, which is used to guide the engagement between the slide bar 11 and the first slide groove 10, during the installation of the blade 2, the slide bar 11 first engages with the guide groove 12. As the blade 2 gradually extends into the placement cavity 5, the slide bar 11 slides through the guide groove 12 and then engages with the first slide groove 10, thereby gradually increasing the engagement area between the slide bar 11 and the first slide groove 10, thus improving the stability of the engagement between the slide bar 11 and the first slide groove 10.

[0033] In a preferred embodiment, based on the above method, the unlocking member 4 further includes a first abutting member 13, which is located on the housing 1. After the protective member 3 extends into the housing 1, the first abutting member 13 abuts against the protective member 3, so that when the blade 2 extends out from the head 6 of the housing, the protective member 3 is located inside the housing 1.

[0034] Furthermore, by setting the first abutment 13, after the protective member 3 extends into the housing 1, the first abutment 13 abuts against the protective member 3, thereby restricting the movement of the protective member 3. As a result, when the blade 2 extends out from the head 6 of the housing, it is easier to keep the protective member 3 inside the housing 1, thereby improving the stability of the protective member 3 when it is placed inside the housing 1, and making it easier for the blade that is not protected by the protective member 3 to extend out from the head 6 of the housing.

[0035] As a preferred embodiment, based on the above method, the protective member 3 is further provided with a second abutment 14. During the process of the blade 2 separating from the housing 1, the blade 2 is pulled out from the tail 7 of the housing, and the second abutment 14 abuts against the blade 2, so that the blade 2 and the protective member 3 move synchronously. After the protective component 3 is released from its engagement with the unlocking component 4, the protective component 3 gradually recovers its deformation, reducing the width h of the clamping area. The two clamping plates 8 resume clamping the blade 2, and the protective component 3 resumes protection of the blade.

[0036] Furthermore, by setting a second stop 14, during the separation of the blade 2 from the housing 1, the blade 2 is pulled out from the tail 7 of the housing, and the second stop 14 abuts against the blade 2, so that the blade 2 and the protective member 3 move synchronously. At the same time, after the protective member 3 is released from its engagement with the unlocking member 4, the protective member 3 gradually restores its deformation, reducing the width h of the clamping area. The two clamping plates 8 gradually resume clamping the blade 2, so that the protective member 3 restores its protection of the blade edge, and all parts of the blade edge can be protected by the protective member 3, thereby improving the safety when replacing the blade 2. The second stop 14 is located at the end of the protective member 3, and the second stop 14 is used to abut against the tail of the blade 2.

[0037] As a preferred embodiment, based on the above method, the blade 2 is further provided with a gripping part 15, which is used by the operator to grip. After the operator grips the gripping part 15, the operator can insert the blade 2 from the tail of the housing 7 into the placement cavity 5, or pull the blade 2 in the placement cavity 5 out from the tail of the housing 7.

[0038] Furthermore, by providing the grip part 15, the convenience for medical staff to install the blade 2 on the housing 1 and to replace the blade 2 on the housing 1 is further improved.

[0039] As a preferred embodiment, based on the above method, the blade 2 is further provided with a through hole 16, and the housing 1 is provided with a knob 17. The knob 17 is used to pass through the through hole 16 and cooperate with the blade 2. The knob 17 is slidably disposed on the housing 1. When the knob 17 slides relative to the housing 1, the sliding direction is the same as the length direction of the housing 1. When the knob 17 slides relative to the housing 1, the knob 17 and the blade 2 move synchronously, so that the blade 2 extends out of the housing 1 or retracts into the housing 1.

[0040] Furthermore, by setting a knob 17, which passes through the through hole 16 and cooperates with the blade 2, the knob 17 and the blade 2 move synchronously when the knob 17 slides relative to the housing 1, thereby facilitating the extension or retraction of the blade 2 from the housing 1 and improving the convenience of controlling the extension amount of the blade 2 when it extends from the housing 1.

[0041] As a preferred embodiment, based on the above method, the housing 1 is further provided with a second sliding groove 18, the length direction of the second sliding groove 18 is in the same direction as the length direction of the housing 1, the knob 17 cooperates with the second sliding groove 18, the knob 17 can slide relative to the housing 1 along the length direction of the second sliding groove 18, the knob 17 includes a knob part 19 and a knob part 20, the knob part 19 and the knob part 20 are threadedly detachably connected; When the knob part 19 and the knob part 20 are connected, the knob part 19 is rotated relative to the knob part 20 to make the knob part 19 and the knob part 20 cooperate to clamp or release the housing 1. When the knob part 19 and the knob part 20 are separated, the knob part 19 and the knob part 20 can be removed from the housing 1.

[0042] Furthermore, by setting a knob part 19 and a knob part 20, when the knob part 19 and the knob part 20 are connected, the knob part 19 rotates relative to the knob part 20, so that the knob part 19 and the knob part 20 cooperate to clamp or release the housing 1. Thus, when the knob part 19 and the knob part 20 release the housing 1, the knob 17 can slide along the length direction of the second slide groove 18, thereby driving the blade 2 to move, changing the length of the blade 2 extending out of the housing 1. By rotating knob 19 relative to knob 20, knob 19 and knob 20 cooperate to clamp housing 1, thereby fixing knob 17 and blade 2 relative to housing 1, thus improving the stability of blade 2 when it extends from housing head 6; at the same time, after knob 19 and knob 20 are separated, knob 19 and knob 20 can be removed from housing 1, thereby disengaging knob 17 from blade 2, thus facilitating replacement of blade 2.

[0043] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
