Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to an improved anti-splash biopsy cap. Background Art

[0002] During biopsy, the biopsy port is generally provided with a biopsy cap, and the cap body is provided with a cap cover. When performing a biopsy operation, the cap cover is opened, and the biopsy forceps are inserted through the biopsy channel on the cap body and the operation is performed.

[0003] Publication number CN215227469U, publication date 2021-12-21, discloses an anti-splash protective film for an endoscopic biopsy cap, including a gasket, an outer wall of one side of the gasket is fixedly connected to a fitting tube, and the inner wall of the fitting tube is fixedly connected to a multi-layer sealing film, the materials of the gasket, fitting tube and sealing film are all sterile rubber suitable for medical applications, and the thickness of the sealing film 3 is 0.6-1.0mm.

[0004] In the prior art including the above-mentioned patent, by setting the thickness of the sealing film to 0.6-1.0mm, the rubber of this thickness has very high softness and dexterity, which can seal the needle hole. When one layer of the needle hole is accidentally enlarged, when the mixture flows through this layer of sealing film, the sealing film behind it will also isolate it to prevent the mixture from leaking. However, since the thickness of the sealing film is very thin, when the biopsy forceps is pulled out, the needle hole is easily squeezed, deformed or even worn by the biopsy forceps, and a gap is generated between the needle hole and the biopsy line, resulting in a small amount of the mixture still splashing out when the biopsy forceps is pulled out, and the anti-splashing effect is poor. Utility Model Content

[0005] The utility model aims to provide an improved anti-splash biopsy cap, which is used to solve the problem of poor anti-splash effect in the prior art.

[0008] The pressing mechanism is symmetrically arranged in the biopsy cap, and the pressing mechanism includes a push plate, and the push plate is driven to squeeze the biopsy tube to deform the first anti-splashing membrane and the second anti-splashing membrane.

[0009] Preferably, an anti-splashing cavity is provided between the first anti-splashing film and the second anti-splashing film.

[0010] Preferably, the pressing mechanism further includes a push pin and a spring.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-6 As shown, an improved anti-splash biopsy cap includes a biopsy cap 1 and further includes:

[0026] The biopsy tube 3 is provided with a spray prevention structure 4 therein, the spray prevention structure 4 comprises a first spray prevention film 41 and a second spray prevention film 42 which are symmetrically arranged, and the first spray prevention film 41 and the second spray prevention film 42 are both inclinedly arranged to form a V-shaped structure abutting against each other;

[0027] The pressing mechanism 8 is symmetrically arranged in the biopsy cap 1 . The pressing mechanism 8 comprises a push plate 81 . The push plate 81 is driven to squeeze the biopsy tube 3 to deform the first anti-splashing membrane 41 and the second anti-splashing membrane 42 .

[0028] Specifically, an anti-splashing cavity 43 is provided between the first anti-splashing film 41 and the second anti-splashing film 42 . The biopsy tube 3, the first anti-splash membrane 41 and the second anti-splash membrane 42 are an integrally formed rubber structure. When in use, the biopsy forceps are passed through the first wire groove 411 and the second wire groove 421 provided on the first anti-splash membrane 41 and the second anti-splash membrane 42 so that the jaws of the biopsy forceps enter the biopsy tube 3. Since the first anti-splash membrane 41 and the second anti-splash membrane 42 are both V-shaped structures abutting against each other, when the biopsy wire enters the first wire groove 411 and the second wire groove 421 in turn, the groove walls of the first wire groove 411 and the second wire groove 421 are squeezed and deformed by the biopsy wire, and the groove walls of the first wire groove 411 and the second wire groove 421 recover their deformation and fit tightly with the biopsy wire, thereby eliminating the gap between the groove walls of the first wire groove 411 and the second wire groove 421 and the biopsy wire, ensuring the sealing of the biopsy tube 3 during biopsy and preventing secretions in the patient's body from being sprayed out during biopsy.

[0029] During biopsy, due to the internal pressure of the patient, the internal gas and secretions will flow back. The second anti-splash membrane 42 is designed to be abutted against each other in a V-shaped structure, such as Figure 2 As shown, when the gas-accompanied secretions flow back into the biopsy tube 3, since the second line groove 421 of the second anti-splashing membrane 42 is sealed with the biopsy line and the second anti-splashing membrane 42 is in a V-shaped structure, the gas-accompanied secretions will disperse and flow along the V-shaped wall at the bottom of the second anti-splashing membrane 42 and gather in the gap between the biopsy tube 3 and the V-shaped wall at the bottom of the second anti-splashing membrane 42, thereby increasing the pressure in the gap between the biopsy tube 3 and the V-shaped wall at the bottom of the second anti-splashing membrane 42, thereby applying radial pressure to the V-shaped wall at the bottom of the second anti-splashing membrane 42, so that the two second anti-splashing membranes 42 are more closely abutted against each other, and at the same time, the groove wall of the second line groove 421 is more closely fitted to the biopsy line, thereby further enhancing the sealing effect, effectively preventing the gas-accompanied secretions from being sprayed out, and further enhancing the anti-splashing effect of the biopsy cap 1.

[0030] Since the gas-accompanying secretions will disperse and flow along the V-shaped wall at the bottom of the second anti-splash membrane 42 and gather in the gap between the biopsy tube 3 and the V-shaped wall at the bottom of the second anti-splash membrane 42, the pressure in the gap between the biopsy tube 3 and the V-shaped wall at the bottom of the second anti-splash membrane 42 increases, so that the groove wall of the second wire groove 421 fits more closely with the biopsy wire. Since the jaw diameter of the biopsy forceps is larger than the diameter of the biopsy wire, when the biopsy wire is pulled out, the jaws will be stuck at the second wire groove 421. If the jaws are forcibly pulled out, the sampled tissue at the jaws may fall off due to the resistance of the second wire groove 421, and the groove wall of the second wire groove 421 will be worn due to friction with the biopsy wire. Therefore, a pressing mechanism 8 is provided to drive the push plate 81 to move toward the biopsy tube 3, so that the push plate 81 squeezes the biopsy tube 3 to deform, so that the first anti-splash membrane 41 and the second anti-splash membrane 42 are compressed and deformed at the same time, so that the first wire groove 411 and the second wire groove 421 are deformed. Figure 4 to Figure 5 As shown, the apertures of the first wire groove 411 and the second wire groove 421 are enlarged, and the groove walls of the first wire groove 411 and the second wire groove 421 are separated from the biopsy wire to reduce wear, while facilitating the removal of the jaws without causing the sampled tissue to fall off, thereby effectively improving the success rate of sampling and the service life of the biopsy cap 1.

[0031] Furthermore, when the biopsy forceps is taken out, the apertures of the first wire groove 411 and the second wire groove 421 become larger. After the groove wall of the second wire groove 421 is separated from the biopsy wire, part of the sealed material will still be ejected from the gap between the groove wall of the second wire groove 421 and the biopsy wire as the biopsy forceps is taken out. Therefore, the first anti-splashing film 41 is provided and cooperates with the second anti-splashing film 42 to form an anti-splashing cavity 43. The secretions follow the biopsy forceps at the second wire groove 421 and are scattered and ejected onto the cavity wall of the anti-splashing cavity 43. Figure 6 As shown, the first anti-splashing film 41 is further shielded to effectively prevent the secretions from being sprayed out along with the biopsy forceps during removal, thereby preventing the secretions from being splashed during and at the end of the biopsy.

[0032] In the above technology, the anti-splash structure 4 and the pressing mechanism 8 are provided, and the first anti-splash film 41 and the second anti-splash film 42 are both inclinedly arranged to form a V-shaped structure abutting against each other, thereby eliminating the gap between the first anti-splash film 41 and the second anti-splash film 42 and the biopsy line. The double sealing design ensures the sealing of the biopsy tube 3 during the biopsy to prevent the secretions in the patient's body from being sprayed out during the biopsy. During the biopsy, due to the internal pressure of the patient, the internal gas will flow back along with the secretions, and the second anti-splash film 42 abuts against each other. Due to the design of the V-shaped structure, when the gas accompanied by secretions flows back into the biopsy tube 3, the gas accompanied by secretions will disperse and flow along the V-shaped wall at the bottom of the second anti-splashing film 42 and gather in the gap between the biopsy tube 3 and the V-shaped wall at the bottom of the second anti-splashing film 42, thereby increasing the pressure in the gap between the biopsy tube 3 and the V-shaped wall at the bottom of the second anti-splashing film 42, thereby applying radial pressure to the V-shaped wall at the bottom of the second anti-splashing film 42, so that the two second anti-splashing films 42 are more closely abutted against each other, thereby further enhancing the sealing effect. The anti-splashing effect of the biopsy cap 1 is further enhanced by driving the push plate 81 to move toward the biopsy tube 3, so that the push plate 81 squeezes the biopsy tube 3 and deforms it, so that the first anti-splashing film 41 and the second anti-splashing film 42 are compressed and deformed at the same time, so that the first anti-splashing film 41 and the second anti-splashing film 42 are separated from the biopsy line to reduce wear, and at the same time, it is convenient to remove the jaws without causing the sampled tissue to fall off, effectively improving the success rate of sampling and the service life of the biopsy cap 1, and ... Cooperating with the second anti-splashing film 42, an anti-splashing cavity 43 is formed, and the secretions are scattered along with the biopsy forceps and sprayed onto the cavity wall of the anti-splashing cavity 43, and are further blocked by the first anti-splashing film 41, thereby effectively preventing the secretions from being sprayed out along with the biopsy forceps during removal, thereby achieving anti-splashing of secretions both during and at the end of the biopsy process. Compared with the prior art, it not only has a simple structure, but also has a good sealing effect and a long service life, and can prevent splashing both during and at the end of the biopsy process, thereby greatly improving the anti-splashing effect of the biopsy cap 1.

[0033] As a further embodiment of the present invention, the pressing mechanism 8 further includes a push post 83 and a spring 82 .

[0034] Specifically, by pushing the push post 83 by hand, the push post 83 pushes the push plate 81 to move toward the biopsy tube 3 and squeezes the spring 82, so that the push plate 81 squeezes the biopsy tube 3 and deforms, so that the first anti-splash film 41 and the second anti-splash film 42 are compressed and deformed at the same time, so that the first wire groove 411 and the second wire groove 421 are deformed, as shown in FIG. Figure 4 to Figure 5As shown, the apertures of the first wire groove 411 and the second wire groove 421 are enlarged, and the groove walls of the first wire groove 411 and the second wire groove 421 are separated from the biopsy wire to reduce wear, while facilitating the removal of the jaws without causing the sampled tissue to fall off, thereby effectively improving the success rate of sampling and the service life of the biopsy cap 1.

[0035] As a further embodiment of the present invention, a threaded connection groove 5 is provided in the biopsy cap 1 , and a sealing gasket 51 is fixedly connected to the groove wall at the top of the threaded connection groove 5 .

[0036] Specifically, the biopsy cap 1 can be threadedly installed through the threaded connection groove 5, which is convenient for replacing the biopsy cap 1. At the same time, the provided sealing gasket 51 can seal the connection of the biopsy cap 1 and prevent the biopsy cap 1 from loosening.

[0037] As a further embodiment of the present invention, a biopsy port 2 is provided on the top of the biopsy cap 1 , and anti-slip strips 11 are provided on the outer wall of the biopsy cap 1 in a circumferential array.

[0038] Specifically, the anti-slip strip 11 is provided to facilitate the rotation of the biopsy cap 1 without slipping during installation.

[0039] As a further embodiment of the present invention, the present invention further comprises a cap 7 , on which a sealing plug 71 and a convex plate 72 are provided.

[0040] Specifically, the cap 7 is connected to the biopsy cap 1 through the connecting strip 6, and the biopsy port 2 on the biopsy cap 1 can be sealed by the sealing plug 71 on the cap 7 to prevent dust and bacteria from entering the biopsy tube 3 through the biopsy port 2 when not in use, thereby contaminating the biopsy cap 1 and affecting its use.

[0041] Working principle: The biopsy tube 3, the first anti-splash membrane 41 and the second anti-splash membrane 42 are an integrally formed rubber structure. When in use, the biopsy forceps are passed through the first wire groove 411 and the second wire groove 421 provided on the first anti-splash membrane 41 and the second anti-splash membrane 42, so that the jaws of the biopsy forceps enter the biopsy tube 3. Since the first anti-splash membrane 41 and the second anti-splash membrane 42 are both V-shaped structures abutting against each other, when the biopsy wire enters the first wire groove 411 and the second wire groove 421 in turn, the first wire groove 411 and the second wire groove 421 are The groove wall of the groove 421 is squeezed and deformed by the biopsy line, and the groove walls of the first line groove 411 and the second line groove 421 recover their deformation and fit closely with the biopsy line, thereby eliminating the gap between the groove walls of the first line groove 411 and the second line groove 421 and the biopsy line, ensuring the sealing of the biopsy tube 3 during biopsy, and preventing the secretions in the patient's body from being sprayed out during biopsy. During biopsy, due to the pressure inside the patient, the internal gas will flow back along with the secretions. The second anti-splashing film 42 is designed to have a V-shaped structure that abuts against each other, such as Figure 2As shown, when the gas-accompanied secretion flows back into the biopsy tube 3, since the second line groove 421 of the second anti-splashing film 42 is sealed with the biopsy line, and the second anti-splashing film 42 is in a V-shaped structure, the gas-accompanied secretion will disperse and flow along the V-shaped wall at the bottom of the second anti-splashing film 42 and gather in the gap between the biopsy tube 3 and the V-shaped wall at the bottom of the second anti-splashing film 42, thereby increasing the pressure in the gap between the biopsy tube 3 and the V-shaped wall at the bottom of the second anti-splashing film 42, thereby applying radial pressure to the V-shaped wall at the bottom of the second anti-splashing film 42, so that the two second anti-splashing films 42 are more closely abutted against each other, and at the same time, the groove wall of the second line groove 421 is more closely fitted to the biopsy line, thereby further enhancing the sealing effect, effectively preventing the gas-accompanied secretion from being sprayed out, and further enhancing the anti-splashing effect of the biopsy cap 1. The liquid disperses and gathers in the gap between the biopsy tube 3 and the V-shaped wall at the bottom of the second anti-splashing membrane 42, thereby increasing the pressure in the gap between the biopsy tube 3 and the V-shaped wall at the bottom of the second anti-splashing membrane 42, so that the groove wall of the second wire groove 421 fits the biopsy wire more closely. Since the jaw diameter of the biopsy forceps is larger than the diameter of the biopsy wire, when the biopsy wire is pulled out, the jaws will be stuck at the second wire groove 421. If the jaws are forcibly pulled out, the sampled tissue at the jaws may fall off due to the resistance of the second wire groove 421, and the groove wall of the second wire groove 421 will be worn due to friction with the biopsy wire. Therefore, a pressing mechanism 8 is provided to drive the push plate 81 to move toward the biopsy tube 3, so that the push plate 81 squeezes the biopsy tube 3 to deform, so that the first anti-splashing membrane 41 and the second anti-splashing membrane 42 are compressed and deformed at the same time, so that the first wire groove 411 and the second wire groove 421 are deformed. Figure 4 to Figure 5 As shown, the apertures of the first wire groove 411 and the second wire groove 421 are enlarged, and the groove walls of the first wire groove 411 and the second wire groove 421 are separated from the biopsy line to reduce wear, and at the same time, it is convenient to remove the jaws without causing the sampled tissue to fall off, effectively improving the success rate of sampling and the service life of the biopsy cap 1. In addition, when the biopsy forceps are removed, the apertures of the first wire groove 411 and the second wire groove 421 are enlarged, and after the groove wall of the second wire groove 421 is separated from the biopsy line, part of the sealed material will still be taken out with the biopsy forceps and sprayed out from the gap between the groove wall of the second wire groove 421 and the biopsy line. Therefore, a first anti-splashing film 41 is provided and cooperates with the second anti-splashing film 42 to form an anti-splashing cavity 43. The secretions follow the biopsy forceps at the second wire groove 421 and are scattered and sprayed onto the cavity wall of the anti-splashing cavity 43, as shown in FIG. Figure 6 As shown, the first anti-splashing film 41 is further shielded to effectively prevent the secretions from being sprayed out along with the biopsy forceps during removal, thereby preventing the secretions from being splashed during and at the end of the biopsy.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
