Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically relates to an intemal medicine tumor administration device. Background Art

[0002] The oncology department, like the departments of gynecology, pediatrics, internal medicine, and surgery, is a secondary discipline of clinical medicine. The oncology department is further divided into medical oncology, radiotherapy oncology, and surgical oncology. Medical oncology mainly focuses on the medical treatment of various benign or malignant tumors.

[0003] In the existing medical oncology treatment methods, the condition is generally controlled through drugs, and cytotoxic drugs, hormonal drugs, biological response modifiers, monoclonal antibody drugs, other types of drugs, and adjuvants are used to treat patients.

[0004] In the existing drug treatments, the medication cycle is long, the onset is relatively slow, and it will also cause harm to the healthy tissues of patients. In order to improve the effect of drugs, shorten the time required for the drugs to take effect, and reduce the harm to the healthy tissues of patients, an accurate drug administration device is needed.

[0005] Therefore, the present invention provides an internal medicine tumor administration device. Summary of the Invention

[0006] In order to make up for the deficiencies of the existing technology and solve at least one of the technical problems proposed in the background art.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: An internal medicine tumor administration device of the present invention includes a handle; a connection seat is installed at the top of the handle; a sleeve rod is fixedly connected to the end of the connection seat away from the handle; a syringe barrel is arranged at the end of the sleeve rod away from the connection seat; a syringe is installed on the surface of the connection seat; the syringe and the syringe barrel are connected through a catheter; during operation, in the process of treating cancer, common drugs are mostly taken orally or injected, and the liquid medicine cannot directly act on the tumor. Therefore, the embodiment of the present invention can be used. First, a doctor needs to determine the tumor location of the patient and perform a minimally invasive surgery on the patient's body surface, make a minimally invasive incision on the patient's body surface, then insert the sleeve rod into the patient's body, control the direction of the sleeve rod through the handle, so that the needle at the end of the sleeve rod can pierce into the tumor in the patient's body. After that, the doctor pushes the syringe to inject the liquid medicine in the syringe into the tumor in the patient's body, thereby achieving the purpose of accurate drug administration, enabling the drug to directly act on the tumor in the patient's body, and then shortening the time required for the drug to take effect and reducing the harm to the healthy tissues of the patient.

[0008] Preferably, a plurality of evenly arranged rotating grooves are provided on the end surface of the sleeve rod away from the handle; a push rod is connected to the rotating groove via a torsion spring; a pull rope is fixedly connected to one end of the push rod close to the sleeve rod; the pull rope is twisted into a strand inside the sleeve rod; a grip is rotatably connected to the surface of the handle; the top of the grip is fixedly connected to the pull rope; during operation, when the patient's tumor is located deeper in the body and is blocked by other tissues of the patient, the doctor can pinch the grip and make the grip rotate on the surface of the handle, and by rotating the grip, the pull rope is driven to move in the direction of the handle, thereby driving the push rod to rotate in the rotating groove, and through the rotating push rod, the tissue blocking the tumor is pushed away, so that the needle can smoothly penetrate into the tumor, thereby reducing damage to the patient's healthy tissue.

[0009] Preferably, one end of the inner wall of the rotating groove close to the inside of the sleeve rod is rotatably connected to a guide wheel; an annular groove is provided on the side surface of the guide wheel; the pull rope is in contact with the bottom of the annular groove; during operation, the doctor pinches the handle to pull the pull rope, and the pulled pull rope slides between the arc groove on the surface of the guide wheel, thereby avoiding direct contact between the pull rope and the edge of the groove, thereby preventing the pull rope from breaking due to continuous friction between the pull rope and the edge of the groove, thereby extending the service life of the pull rope.

[0010] Preferably, the outer surface of the push rod is fixedly connected with a baffle; the side surface of the baffle away from the push rod is fixedly connected with a silicone pad; the surface of the silicone pad is fixedly connected with a plurality of evenly arranged raised particles; during operation, when the push rod rotates, the baffle on the surface of the push rod will lift up other tissues in the patient's body to expose the tumor, and at the same time, the silicone pad on the surface of the baffle is relatively soft and not easy to damage the patient's healthy tissue, and the raised particles on the surface of the silicone pad can increase the roughness of the surface of the silicone pad, thereby increasing the friction of the surface of the silicone pad and preventing the patient's tissue from slipping off the surface of the silicone pad.

[0011] Preferably, a plurality of evenly arranged connecting rods are fixedly connected to the surface of the sleeve rod; an arc-shaped buckle is provided at one end of the connecting rod away from the sleeve rod; during operation, when the patient's tumor is located deeper in the body, the doctor can clamp the endoscope tube of the endoscope on the arc-shaped buckle, so that the doctor can observe the patient's body through the endoscope, locate the position of the tumor more accurately, and facilitate the doctor to perform subsequent drug injection.

[0012] Preferably, the top surface of the connecting rod near the top rod is threadedly connected to a support rod; a spherical joint is installed between the top surface of the support rod and the arc-shaped buckle; during operation, when installing the endoscope, the doctor rotates the support rod to adjust the height of the endoscope lens, and then adjusts the direction of the endoscope lens through the spherical joint so that the endoscope lens points to the syringe, thereby allowing the doctor to obtain a better field of view, further facilitating the doctor's subsequent drug injection.

[0013] Preferably, a corrugated pipe is fixedly connected between the sleeve rod and the syringe barrel; a pull rod is arranged between the ejector rod and the syringe barrel; the pull rod is rotatably connected to the top; the pull rod is rotatably connected to the surface of the syringe barrel; during operation, when the doctor pinches the handle, driving the ejector rod to rotate in a mutually away direction, the ejector rod will drive the pull rod, and the pull rod will pull the syringe barrel, making the syringe barrel away from the sleeve rod and stretching the corrugated pipe, thereby increasing the length of the syringe barrel, facilitating the doctor to insert the syringe barrel into the tumor, and avoiding the inability to administer medicine normally due to the insufficient length of the syringe barrel.

[0014] Preferably, a blocking rod is fixedly connected to the end face of the sleeve rod inside the corrugated pipe; a rubber pad is fixedly connected to one end of the syringe barrel close to the corrugated pipe; a through hole is opened on the end face of the rubber; during operation, when the syringe barrel moves away from the sleeve rod, the syringe barrel will drive the rubber pad away from the blocking rod, enabling the liquid medicine to flow into the syringe barrel through the through hole, and when the doctor does not pinch the handle, the ejector rod does not rotate, and at this time, the blocking rod abuts against the surface of the rubber pad, preventing the liquid medicine from flowing out through the syringe barrel, thereby preventing the leakage of the liquid medicine during the doctor's preparation period.

[0015] Preferably, the sleeve rod includes a plurality of uniformly arranged metal sleeve rings; a silica gel sleeve is fixedly connected between the metal sleeve rings; during operation, through the connection of the plurality of metal rings and the silica gel sleeve, the connection part has elasticity and can deform and bend, so that the composed sleeve rod can extend deep into the patient's body and bend itself to avoid the patient's healthy tissues as much as possible, thereby reducing the harm to the patient's healthy tissues.

[0016] Preferably, a sleeve is fixedly connected to the surface of the connecting seat at the position of the syringe; a heating wire is fixedly connected to the inner wall of the sleeve; the syringe is installed inside the sleeve; during operation, before the liquid medicine injection is required, the liquid medicine can be heated by the heating wire on the inner wall of the sleeve to make the temperature of the liquid medicine as close as possible to the temperature inside the human body, avoiding the discomfort of the patient due to the too low temperature of the liquid medicine.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. For a tumor internal medicine administration device described in the present invention, the direction of the sleeve rod is controlled by the handle, so that the needle at the end of the sleeve rod can be inserted into the tumor in the patient's body. Then the doctor pushes the syringe to inject the liquid medicine in the syringe into the tumor in the patient's body, thereby achieving the purpose of precise drug administration, enabling the drug to directly act on the tumor in the patient's body, thereby shortening the time required for the drug to take effect and reducing the harm to the patient's healthy tissues.

[0019] 2. The oncology internal medicine drug delivery device described in the present invention drives the pull rope to move toward the handle by rotating the grip, thereby driving the push rod to rotate in the rotating groove, and the rotating push rod pushes away the tissue blocking the tumor, allowing the needle to smoothly penetrate into the tumor, thereby reducing damage to the patient's healthy tissue.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Embodiment 1

[0032] like Figure 1As shown, an oncology medication device according to an embodiment of the present invention comprises a handle 1, a connection seat 2, a sleeve rod 3, a syringe 4 and a syringe 5; the syringe 5 is a prior art and can be assembled and disassembled with the surface of the connection seat 2; the connection seat 2 is installed on the top of the handle 1; the sleeve rod 3 is fixedly connected to the end of the connection seat 2 away from the handle 1; the syringe 4 is arranged at the end of the sleeve rod 3 away from the connection seat 2; the syringe 5 is installed on the surface of the connection seat 2; the syringe 5 is connected to the syringe 4 through a catheter; when working, in the process of treating cancer, common drugs are mostly taken orally or injected, and neither of them can make the drug liquid act directly on The embodiment of the present invention can be used for this purpose. First, the doctor needs to determine the location of the patient's tumor and perform minimally invasive surgery on the patient's body surface. A minimally invasive incision is made on the patient's body surface, and then the sleeve rod 3 is extended into the patient's body. The direction of the sleeve rod 3 is controlled by the handle 1 so that the needle at the end of the sleeve rod 3 can be inserted into the tumor in the patient's body. Then the doctor pushes the syringe 5 to inject the liquid medicine in the syringe 5 into the tumor in the patient's body, thereby achieving the purpose of precise drug administration, so that the drug can directly act on the tumor in the patient's body, thereby shortening the time required for the drug to take effect and reducing the damage to the patient's healthy tissues.

[0033] like Figures 1 to 2 As shown, the end surface of the sleeve rod 3 away from the handle 1 is provided with a plurality of evenly arranged rotating grooves 6; the rotating groove 6 is connected to a push rod 7 through a torsion spring; the push rod 7 is fixedly connected to a pull rope 8 at one end close to the sleeve rod 3, and the pull rope 8 is not elastic; the pull rope 8 is twisted into a strand inside the sleeve rod 3; a grip 9 is rotatably connected to the surface of the handle 1; the top of the grip 9 is fixedly connected to the pull rope 8; during operation, when the patient's tumor is located deeper in the body and is blocked by other tissues of the patient, the doctor can pinch the grip 9 and make the grip 9 rotate on the surface of the handle 1, and by rotating the grip 9, the pull rope 8 is driven to move toward the direction of the handle 1, thereby driving the push rod 7 to rotate in the rotating groove 6, and through the rotating push rod 7, the tissue blocking the tumor is pushed away, so that the needle can smoothly penetrate into the tumor, thereby reducing damage to the patient's healthy tissue.

[0034] like Figures 1 to 2 As shown, the inner wall of the rotating groove 6 is rotatably connected to one end of the sleeve rod 3 with a guide wheel 10; the side surface of the guide wheel 10 is provided with an annular groove 11; the pull rope 8 is in contact with the bottom of the annular groove 11, and the bottom of the annular groove 11 is relatively smooth; when working, the doctor pinches the handle 9 to pull the pull rope 8, and the pulled pull rope 8 slides against the arc groove on the surface of the guide wheel 10, thereby avoiding direct contact between the pull rope 8 and the edge of the groove, thereby preventing the pull rope 8 from breaking due to continuous friction between the pull rope 8 and the edge of the groove, thereby extending the service life of the pull rope 8.

[0035] like Figures 2 to 3As shown, baffles 12 are fixedly connected to the outer surfaces of the ejector rods 7; a silica gel pad 13 is fixedly connected to the surface of the baffle 12 away from the ejector rod 7, and the silica gel pad 13 is elastic; a plurality of uniformly arranged raised particles 14 are fixedly connected to the surface of the silica gel pad 13. During operation, when the ejector rod 7 rotates, the baffle 12 on the surface of the ejector rod 7 will push up other tissues in the patient's body, exposing the tumor. At the same time, the silica gel pad 13 on the surface of the baffle 12 is relatively soft and not likely to harm the patient's healthy tissues. The raised particles 14 on the surface of the silica gel pad 13 can increase the roughness of the surface of the silica gel pad 13, thereby increasing the friction on the surface of the silica gel pad 13 and preventing the patient's tissues from slipping off the surface of the silica gel pad 13.

[0036] As Figure 1 shown, a plurality of uniformly arranged connecting rods 15 are fixedly connected to the surface of the sleeve rod 3; an arc-shaped buckle 16 is arranged at one end of the connecting rod 15 away from the sleeve rod 3; the arc-shaped buckle 16 is made of an elastic material. During operation, when the patient's tumor is deep in the body, the doctor can clamp the mirror tube of the endoscope on the arc-shaped buckle 16, so that the doctor can observe the patient's body through the endoscope, more accurately locate the position of the tumor, and facilitate the doctor to perform subsequent drug injection.

[0037] As Figure 1 and Figure 4 shown, a support rod 17 is threadedly connected to the top surface of the connecting rod 15 close to the ejector rod 7; a spherical joint 18 is installed between the top surface of the support rod 17 and the arc-shaped buckle 16. During operation, when installing the endoscope, the doctor can rotate the support rod 17 to adjust the height of the endoscope lens, and then adjust the orientation of the endoscope lens through the spherical joint 18, so that the endoscope lens points to the syringe 4, enabling the doctor to obtain a better view and further facilitating the doctor to perform subsequent drug injection.

[0038] As Figures 1 to 2 shown, a corrugated pipe 19 is fixedly connected between the sleeve rod 3 and the syringe 4; the corrugated pipe 19 can be stretched; a pull rod 20 is arranged between the ejector rod 7 and the syringe 4; the pull rod 20 is rotatably connected to the top; the pull rod 20 is rotatably connected to the surface of the syringe 4. During operation, when the doctor squeezes the grip 9, driving the ejector rod 7 to rotate in a mutually separated direction, the ejector rod 7 will drive the pull rod 20, and the pull rod 20 will pull the syringe 4, causing the syringe 4 to move away from the sleeve rod 3 and stretching the corrugated pipe 19, thereby increasing the length of the syringe 4, facilitating the doctor to insert the syringe 4 into the tumor and avoiding the inability to administer drugs normally due to the insufficient length of the syringe 4.

[0039] As Figure 2 and Figure 5As shown, a plug rod 21 is fixedly connected to the end face of the sleeve rod 3 inside the corrugated pipe 19; a rubber pad 22 is fixedly connected to one end of the syringe barrel 4 close to the corrugated pipe 19; a through hole 23 is formed in the end face of the rubber; during operation, when the syringe barrel 4 moves away from the sleeve rod 3, the syringe barrel 4 will drive the rubber pad 22 away from the plug rod 21, so that the liquid medicine can flow into the syringe barrel 4 through the through hole 23. When the doctor does not squeeze the grip 9, the ejector rod 7 does not rotate. At this time, the plug rod 21 abuts against the surface of the rubber pad 22, preventing the liquid medicine from flowing out through the syringe barrel 4, thereby preventing the liquid medicine from leaking during the doctor's preparation period.

[0040] As Figure 1 and Figure 6 shown, the sleeve rod 3 includes a plurality of uniformly arranged metal sleeve rings 24 and a silica gel sleeve 25; the silica gel sleeve 25 is fixedly connected between the metal sleeve rings 24; during operation, through the connection of the plurality of metal rings and the silica gel sleeve 25, the connection part has elasticity and can deform and bend, so that the formed sleeve rod 3 can extend deep into the patient's body and bend itself to avoid the patient's healthy tissues as much as possible, thereby reducing the harm to the patient's healthy tissues.

[0041] Embodiment 2

[0042] As Figures 7 to 8 shown, compared with Embodiment 1, another implementation manner of the present invention is: a sleeve 26 is fixedly connected to the surface of the connecting seat 2 at the position of the syringe 5; a heating wire 27 is fixedly connected to the inner wall of the sleeve 26; the syringe 5 is installed inside the sleeve 26; during operation, before the liquid medicine injection is required, the liquid medicine can be heated by the heating wire 27 on the inner wall of the sleeve 26 to make the temperature of the liquid medicine as close as possible to the temperature inside the human body, avoiding the discomfort of the patient due to the too low temperature of the liquid medicine.

[0043] During operation, in the process of treating cancer, common drugs are mostly taken orally or injected, and the liquid medicine cannot directly act on the tumor. Therefore, the embodiment of the present invention can be used. First, the doctor needs to determine the tumor position of the patient and perform a minimally invasive surgery on the patient's body surface, make a minimally invasive incision on the patient's body surface, and then insert the sleeve rod 3 into the patient's body. By controlling the direction of the sleeve rod 3 through the handle 1, the needle at the end of the sleeve rod 3 can be inserted into the tumor in the patient's body. Then the doctor pushes the syringe 5 to inject the liquid medicine in the syringe 5 into the tumor in the patient's body, so as to achieve the purpose of precise drug delivery, make the drug directly act on the tumor in the patient's body, thereby shortening the time required for the drug to take effect and reducing the harm to the patient's healthy tissues.

[0044] When the patient's tumor is located deep within the body and is blocked by other tissues of the patient, the doctor can pinch the grip 9 and cause the grip 9 to rotate on the surface of the handle 1. By rotating the grip 9, the pull rope 8 is driven to move towards the handle 1, thereby driving the ejector rod 7 to rotate within the rotation groove 6. Through the rotating ejector rod 7, the tissues blocking the tumor are pushed aside, enabling the needle to smoothly penetrate into the tumor, thereby reducing the damage to the patient's healthy tissues.

[0045] When the doctor pinches the grip 9 to pull the pull rope 8, a sliding occurs between the pulled pull rope 8 and the arc groove on the surface of the guide wheel 10, thereby avoiding direct contact between the pull rope 8 and the edge of the groove. Furthermore, it prevents the pull rope 8 from breaking due to continuous friction between the pull rope 8 and the edge of the groove, thereby extending the service life of the pull rope 8.

[0046] When the ejector rod 7 rotates, the baffle 12 on the surface of the ejector rod 7 will lift other tissues within the patient's body, exposing the tumor. At the same time, the silica gel pad 13 on the surface of the baffle 12 is relatively soft and not likely to harm the patient's healthy tissues. The raised particles 14 on the surface of the silica gel pad 13 can increase the roughness of the surface of the silica gel pad 13, thereby increasing the friction on the surface of the silica gel pad 13 and preventing the patient's tissues from slipping off the surface of the silica gel pad 13.

[0047] When the patient's tumor is located deep within the body, the doctor can clamp the endoscope tube on the arc-shaped buckle 16, enabling the doctor to observe the patient's body through the endoscope, more accurately locate the position of the tumor, and facilitate subsequent drug injection by the doctor.

[0048] When installing the endoscope, the doctor can rotate the support rod 17 to adjust the height of the endoscope lens, and then adjust the orientation of the endoscope lens through the spherical joint 18, making the endoscope lens point towards the syringe 4, thereby enabling the doctor to obtain a better view and further facilitating subsequent drug injection by the doctor.

[0049] When the doctor pinches the grip 9, driving the ejector rod 7 to rotate in a direction away from each other, the ejector rod 7 will drive the pull rod 20, and the pull rod 20 will pull the syringe 4, causing the syringe 4 to move away from the sleeve rod 3 and stretching the corrugated pipe 19, thereby increasing the length of the syringe 4 and facilitating the doctor to insert the syringe 4 into the tumor, avoiding the inability to administer drugs normally due to insufficient length of the syringe 4.

[0050] When the syringe 4 moves away from the sleeve rod 3, the syringe 4 will carry the rubber pad 22 away from the plug rod 21, enabling the liquid medicine to flow into the syringe 4 through the through hole 23. When the doctor does not pinch the grip 9, the ejector rod 7 does not rotate. At this time, the plug rod 21 presses against the surface of the rubber pad 22, preventing the liquid medicine from flowing out through the syringe 4, thereby preventing the leakage of the liquid medicine during the doctor's preparation period.

[0051] It is connected to the silica gel sleeve 25 through multiple metal rings, so that the connection part has elasticity and can deform and bend. Furthermore, the formed sleeve rod 3 can extend deep into the patient's body and avoid the healthy tissues of the patient as much as possible through its own bending, thereby reducing the harm to the healthy tissues of the patient.

[0052] Before the liquid medicine injection is required, the liquid medicine can be heated by the heating wire 27 on the inner wall of the sleeve 26, so that the temperature of the liquid medicine is as close as possible to the temperature of the human body, avoiding discomfort of the patient due to too low temperature of the liquid medicine.
