DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Embodiment 1 further describes a tumor sampling device for conveniently separating tumors proposed by the present invention, including a support seat 100, an annular cylinder 101 is integrally formed on the upper end surface of the support seat 100, a sleeve 102 is fixedly connected to the middle position of the support seat 100, a hollow hole 103 is arranged in the sleeve 102, and openings 104 are arranged on both sides of the hollow hole 103, an auxiliary sleeve 105 is provided in the movable connecting body in the hollow hole 103, a limiting platform 106 is arranged in the auxiliary sleeve 105, a sampling tube 107 is passed through the limiting platform 106, and the sampling tube 107 includes an inner tube, a sampling needle and a piston plate, so that the piston plate can move in the inner tube through the piston, so that the pressure change of the sampling tube 107 increases, thereby sampling the tumor tissue, and a connecting sleeve 108 is fixedly connected to the bottom end of the support seat 100, and the sampling tube 107 correspondingly passes through the connecting sleeve 108;

[0032] Depend on Figure 1 and Figure 3 It can be seen that the support seat 100 is conical. When in use, the support seat 100 can be attached to the object to be sampled to support the device as a whole. The upper end surface of the support seat 100 is integrally formed with an annular cylinder 101, and the annular cylinder 101 has a cylindrical hole structure. The middle position of the support seat 100 is fixedly connected with a sleeve 102, and a hollow hole 103 and an opening 104 are provided in the sleeve 102. The movable connecting body in the hollow hole 103 has an auxiliary sleeve 105, and the auxiliary sleeve 105 is a hollow structure. 05 is provided with an adjustment mechanism 200 for limiting the movement of the auxiliary sleeve 105 in the vertical direction, and a limiting platform 106 is fixed in the auxiliary sleeve 105, and the limiting platform 106 is used to limit the movement of the sampling tube 107 in the horizontal direction, so that the sampling tube 107 can only move in the vertical direction. At the same time, the present invention is provided with an adjustment mechanism 200 and a separation mechanism 400 in the auxiliary sleeve 105 and the connecting sleeve 108, so that the device can also separate tumor samples when sampling.

[0033] An adjusting mechanism 200 is provided in the auxiliary sleeve 105, and the adjusting mechanism 200 includes a special-shaped piece 201 arranged in the auxiliary sleeve 105. A pressing piece 202 is provided in the annular cylinder 101. The special-shaped piece 201 and the pressing piece 202 cooperate with each other to move the auxiliary sleeve 105. A separation mechanism 400 is also provided in the connecting sleeve 108. The separation mechanism 400 includes a fixing piece 300 arranged in the connecting sleeve 108. A toggle piece 301 is provided in the fixing piece 300. A limit piece 302 is provided in the toggle piece 301. The limit piece 302 is correspondingly arranged in the auxiliary sleeve 105. The pressing piece 202 and the limit piece 302 cooperate to adjust the toggle piece 301.

[0034] Depend on Figures 1 to 5 It can be seen that its adjustment component includes a special-shaped part 201, which is arranged in the auxiliary sleeve 105. The special-shaped part 201 is Z-shaped. The auxiliary sleeve 105 is moved in the vertical direction by cooperating with the pressing part 202 and the special-shaped part 201. When the pressing part 202 moves downward, it drives the auxiliary sleeve 105 to move upward. When the pressing part 202 moves upward, the auxiliary sleeve 105 moves downward. At the same time, the device drives the toggle part 301 to move under the movement of the auxiliary sleeve 105 to separate the sampled objects. In this way, the device can separate the tumor while sampling. The device has a compact structure and is easy to operate, which is convenient for daily work.

[0035] The sampling tube 107 is provided with a splitting mechanism 500, which includes a support member 501 disposed in the sampling tube 107, a splitting member 502 disposed in the support member 501, and an adjusting member 503 for assisting the splitting member 502 disposed in the support member 501. Figures 5 to 8 It can be seen that the present invention sets a support member 501 and a dividing member 502 in the sampling tube 107, so that the adjustment member 503 is displaced in the vertical direction of the support member 501, thereby driving the dividing member 502 to separate the tumor in the sampling tube 107. In this way, the tumor block can be automatically cut and separated during the sampling process, thereby saving time and improving sampling efficiency.

[0036] Working principle: When in use, by setting the sampling tube 107 in the limiting platform 106, the device does not interfere with each other during separation and sampling. When the sampling tube 107 is in use, the sampling tube 107 drives the pressure change through the piston movement inside the inner sleeve, thereby achieving the effect of sampling tumor tissue. At the same time, by setting the adjustment mechanism 200 and the separation mechanism 400, it can promote the effect of tissue breaking and separation of the sampled tissue from the human tissue, improve the sampling efficiency of the sampling tube 107, and avoid the problem of tissue adhesion. In this way, the device can achieve both sampling of tumor tissue and separation of the tumor device.

[0037] Embodiment 2

[0038] The following technical features are added on the basis of Example 1: the special-shaped part 201 includes an inclined groove 201a arranged in the auxiliary sleeve 105, and an inclined plate 201b is movably connected in the inclined groove 201a, and a first contact portion 201c is integrally formed at one end of the inclined plate 201b, and a second contact portion 201d is integrally formed at the other end, one side of the first contact portion 201c is a resistance surface 201e, and the bottom end of the first contact portion 201c is a translation surface 201f, one side of the second contact portion 201d is an extrusion surface 201g, and the bottom end of the second contact portion 201d is a sliding surface 201h, and the translation surface 201f and the sliding surface 201h are attached to the opening 104.

[0039] Depend on Figures 4 to 7 It can be seen from the first embodiment that the auxiliary sleeve 105 is a hollow structure, and an inclined groove 201a is provided on the side wall of the auxiliary sleeve 105. Since the inclined groove 201a is provided on the side wall, the sampling tube 107 is not in the same plane with the auxiliary sleeve 105 when in use, so that the sampling tube 107 will not interfere with movement when in use, and a first contact portion 201c and a second contact portion 201d are formed on both sides of the inclined plate 201b. The inclined plate 201b, the first contact portion 201c and the second contact portion 201d form a Z-shaped structure, and the translation surface 201f and the sliding surface 201h of the first contact portion 201c and the second contact portion 201d are attached to the opening 104, so that the Z-shaped structure can only move horizontally in the opening 104. Since the inclined plate 201b is driven in the inclined groove 201a, the auxiliary sleeve 105 is displaced in the vertical direction through the inclined surface transmission.

[0040] The pressing member 202 includes a cover tube 202a slidably connected in the annular tube 101, and a mounting groove 202b is provided on one side of the cover tube 202a relative to the support seat 100, and a resisting portion 202c and an extruding portion 202d are integrally formed on both sides of the inner wall of the mounting groove 202b, and the side surface of the resisting portion 202c is parallel to the resisting surface 201e, and the side surface of the resisting portion 202c is in contact with the resisting surface 201e, and the side surface of the extruding portion 202d is parallel to the extruding surface 201g, and the side surface of the extruding portion 202d is in contact with the extruding surface 201g, and a partition 202e is fixedly connected to the inner wall of the cover tube 202a, and a compression spring 202f is fixedly connected to the upper end surface of the auxiliary sleeve 105, and the compression spring 202f is a carbon spring with high strength and convenient for daily use, and one end of the compression spring 202f is connected to the top of the inner wall of the partition 202e;

[0041] Depend on Figures 2 to 4It can be known that a cover cylinder 202a is slidably connected inside the annular cylinder 101, and the outer wall of the cover cylinder 202a is attached to the inner wall of the annular cylinder 101. The cover cylinder 202a is connected to the upper end surface of the auxiliary sleeve 105 through a partition 202e and a compression spring 202f. A resistance portion 202c and an extrusion portion 202d are integrally formed on the inner wall of the cover cylinder 202a, and the side surface of the extrusion portion 202d is parallel to the extrusion surface 201g, and the side surface of the extrusion portion 202d is in contact with the extrusion surface 201g. The resistance portion 202c and the extrusion portion 202d limit the Z-shaped structure in Example 1, and when the cover cylinder 202a moves in the vertical direction, the Z-shaped structure moves in the horizontal direction.

[0042] An installation sleeve 202j is provided on the upper end surface of the cover cylinder 202a, and a movable space 202k is formed between the installation sleeve 202j and the cover cylinder 202a. The installation sleeve 202j is arranged on the upper end surface of the annular cylinder 101, and the sampling tube 107 includes a contraction section 202l, and the contraction section 202l is arranged in the movable space 202k. One end of the sampling tube 107 correspondingly passes through the installation sleeve 202j.

[0043] Depend on Figure 2 and Figure 3 It can be seen that a mounting sleeve 202j is fixedly connected to the upper end surface of the cover cylinder 202a, the mounting sleeve 202j is an annular structure, and a movable space 202k is provided between the mounting sleeve 202j and the cover cylinder 202a, the sampling tube 107 includes a contraction section 202l, and the upper end of the sampling tube 107 is fixedly connected to the upper end surface of the cover cylinder 202a, so that when the cover cylinder 202a moves downward, the contraction section 202l of the sampling tube 107 becomes longer at the same time. In this way, in the actual use of sampling and separation, these two operation modes can be operated separately and do not interfere with each other.

[0044] Working principle: When in use, the operator holds the annular tube 101 and aligns it with the part to be sampled. The support seat 100 can be attached to the object to be sampled to ensure the stability of the operation. At this time, the cover tube 202a can be pressed. When the cover tube 202a moves downward, it drives the resistance part 202c and the extrusion part 202d to move synchronously. Since the side of the extrusion part 202d is parallel to the extrusion surface 201g, and the side of the extrusion part 202d is in contact with the extrusion surface 201g, at this time, due to the transmission of the inclined surface, the auxiliary sleeve 105 is driven to move in the vertical direction. Since it is a Z-shaped structure that drives the up and down displacement, and the displacement deviation is small, the auxiliary sleeve 105 is more stable when moving. Compared with directly pressing down, the use structure of this device has better stability and precision, and it is not easy to cause inevitable damage to the tumor due to uneven force on the cover tube 202a, thereby affecting the patient's health.

[0045] Embodiment 3

[0046] The following technical features are added on the basis of the second embodiment: the fixing member 300 includes a reinforcement part 301a fixed on both sides of the inner wall of the connecting sleeve 108, a ring 301b is fixedly connected between the reinforcement parts 301a on both sides, the ring 301b surrounds the sampling tube 107, notches 301c are provided on both sides of the outer wall of the ring 301b, a rotating shaft 301d is rotatably connected in the notch 301c through a bearing, the toggle member 301 includes a separation plate 301e fixedly connected to the rotating shaft 301d, a separation knife 301f is integrally formed at one end of the separation plate 301e, a torsion spring 301g is sleeved on the outer wall of the rotating shaft 301d, the torsion spring 301g is a carbon spring with high strength and convenient for daily use, one end of the torsion spring 301g is fixedly connected to the notch 301c, and the other end of the torsion spring 301g is fixedly connected to the outer wall of the separation plate 301e;

[0047] Depend on Figure 4 and Figure 7 It can be known that reinforcement parts 301a are fixedly connected to both sides of the inner wall of the connecting sleeve 108, and a ring 301b is fixedly connected between the reinforcement parts 301a on both sides. The ring 301b and the reinforcement part 301a form a watch-shaped structure, and the sampling tube 107 correspondingly passes through the ring 301b. At the same time, the present invention further refines the structure of the ring 301b, and notches 301c are provided on both sides of the outer wall of the ring 301b. A rotating shaft 301d is rotatably connected to the notch 301c through a bearing, so that the rotation of the rotating shaft 301d is more stable. A torsion spring 301g is sleeved on the outer wall of the rotating shaft 301d, and the two ends of the torsion spring 301g are respectively fixedly connected to the notch 301c and the separation plate 301e, so that the separation plate 301e on the rotating shaft 301d has better restoring force when in use.

[0048] The limiting member 302 includes an auxiliary groove 302a arranged on the separation plate 301e, and a movable rod 302b is slidably connected in the auxiliary groove 302a. The two ends of the movable rod 302b are respectively fixedly connected to connecting rods 302c, and one end of the connecting rods 302c on both sides is fixedly connected to the inner wall of the auxiliary sleeve 105. Movable openings 302d are provided on both sides of the inner wall of the connecting sleeve 108, and the separation plates 301e on both sides are correspondingly inserted into the movable openings 302d.

[0049] Depend on Figure 7It can be seen that the separation plate 301e is provided with an inclined auxiliary groove 302a, and a movable rod 302b is slidably connected in the auxiliary groove 302a. The movable rod 302b moves in the auxiliary groove 302a as the auxiliary sleeve 105 is displaced in the vertical direction. Since the movable rod 302b is fixedly connected to the auxiliary sleeve 105, the movable rod 302b will not change due to the groove shape of the auxiliary groove 302a. It always moves in the vertical direction. On the contrary, under the deflection force of the inclined auxiliary groove 302a, the separation plate 301e is driven to rotate. When the separation plates 301e on both sides are deflected, they are in a state of being opened or closed, so that the separation plates 301e separate the tumor samples. In this way, the device can both sample the tumor and separate the tumor samples.

[0050] Working principle: It can be seen from Example 2 that when the auxiliary sleeve 105 moves downward, it drives the movable rod 302b on its inner wall connecting rod 302c to move in the vertical direction. At this time, the movable rod 302b slides in the auxiliary groove 302a. Since the auxiliary groove 302a is an inclined surface, and the movable rod 302b is fixedly connected to the inner wall of the auxiliary sleeve 105, the separation plate 301e is rotated through the transmission of the inclined surface. When the separation plate 301e rotates, it drives the rotating shaft 301d to rotate in the notch 301c, and the torsion spring 301g is deformed. The separation knife 301f on the separation plate 301e drives the separation knife 301f on the separation plate 301e to separate the tumor as the auxiliary sleeve 105 moves in the vertical direction. In this way, the device can separate the tumor before sampling. Of course, the device can also be operated during sampling.

An annular groove 501d is provided on the outer wall of the dividing seat 501b, and long auxiliary openings 501e are opened on both sides of the annular groove 501d. A cutting plate 502a is slidably connected in the auxiliary opening 501e, and a limiting opening 502b is provided in the cutting plate 502a. A rubber ring 502c passes through the annular groove 501d and the limiting opening 502b. The rubber ring 502c limits the moving position of the cutting plate 502a, so that when the adjusting member 503 moves in the vertical direction, the cutting plate 502a moves outward or inward.

[0055] The adjusting member 503 includes a conical seat 503a arranged in the slot 501c. The upper end surface of the conical seat 503a is fixedly connected with a clamping rod 503b. The outer wall of the sampling tube 107 is provided with a sliding opening 503c. The clamping rod 503b passes through the sliding opening 503c and is fixedly connected to the inner wall of the auxiliary sleeve 105.

[0056] Depend on Figure 8 It can be seen that the conical seat 503a is a conical structure, and the cross-sectional area gradually decreases from bottom to top. The upper end of the conical seat 503a is fixedly connected with a clamping rod 503b, and the clamping rod 503b is L-shaped. The clamping rod 503b is slidably connected in the sliding opening 503c of the sampling tube 107, and one end of the clamping rod 503b is fixedly connected to the inner wall of the auxiliary sleeve 105. It can be seen from Example 2 that when the pressing member 202 moves in the vertical direction, it will synchronously drive the auxiliary sleeve 105 to move. At this time, the auxiliary sleeve 105 moves in the vertical direction with the pressing member 202, thereby driving the conical seat 503a on the clamping rod 503b to move together;

[0057] Since the conical seat 503a is a conical structure, one end of the cutting plates 502a on both sides is in contact with the conical seat 503a, and the cutting plates 502a are restrained in the auxiliary port 501e by the rubber ring 502c. When the conical seat 503a moves vertically upward in the slot 501c, the contact point between the cutting plates 502a and the conical seat 503a keeps changing, so that the cutting plates 502a expand outward due to the inclined surface of the conical seat 503a. When expanding outward, the tumor is cut into pieces and separated. In this way, the tumor pieces are automatically cut into pieces and separated during the sampling process, thereby saving time and improving the sampling efficiency. When the conical seat 503a moves vertically downward in the slot 501c, the contact area between the cutting plates 502a and the conical seat 503a is reduced. At this time, the rubber ring 502c is stretched and rebounds, thereby driving the cutting plate 502a to retract.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
