A fluorescent laparoscope for clinical surgery of esophageal cancer

Abstract

The present invention discloses a fluorescent laparoscope for clinical surgery of esophageal cancer, which belongs to the field of fluorescent laparoscopes. In the process of inserting the laparoscope body into the laparoscope hole, a locking plate is used to compact the locking rubber block, and the locking rubber block is locally fixed, thereby reducing the movable range of the laparoscope body. When medical staff operate the laparoscope body, when the front end of the laparoscope body rotates in the same plane, the locking plate will not release the locking of the locking rubber block, so that the range of movement of the laparoscope can be reduced in the process of using the laparoscope to find the lesion, and unnecessary harm to the patient is not easily caused due to operating errors. When the laparoscope body needs to be taken out, it only needs to be pulled up. In this process, in order to save effort, the laparoscope body needs to be pulled out in a direction perpendicular to the auxiliary block, which can effectively avoid secondary harm to the patient caused by the laparoscope body during the pulling out process.

Description

Technical Field

[0001] The invention relates to the field of fluorescent laparoscopes, and more specifically to a fluorescent laparoscope used for clinical surgery of esophageal cancer. Background Art

[0002] Fluorescent laparoscope, also known as endoscopic fluorescent angiography imaging system, has the functions of laparoscope imaging system and fluorescent angiography imaging system, providing real-time true high-definition white light and high-definition fluorescent imaging system for laparoscopic surgery. Fluorescent contrast agent combines with proteins in the blood, and is metabolized and excreted by the body, thereby providing lesion inspection in different parts. This enables surgeons to better understand the anatomical structure of tiny, dispersed, hidden and invisible tumor displacement lesions before surgery. The camera adopts advanced sensor technology and specific optical system to provide more realistic color and high-contrast images, with less noise in all precise display modes, so that doctors can better achieve fundamental treatment of tumors during minimally invasive surgery and reduce the risk of complications of minimally invasive surgery.

[0003] Fluorescence laparoscope is an inspection and treatment instrument manufactured according to optical principles. It is based on the selective absorption of light by matter. The monochromator separates the complex light emitted by the light source into monochromatic light. The monochromatic light of a specific wavelength combines with the specific protein components in the blood to produce light reflection. The light is received by the laparoscope objective lens and then converted to photoelectricity by its CCD to form a stained image.

[0004] Fluorescent laparoscopy is actually an upgraded surgical method of laparoscopy. It uses the difference between the metabolic rate of the diseased organ and the normal organ to accumulate a large amount of fluorescent substance in the diseased organ, which is convenient for the doctor to make accurate and rapid judgment on the range of the lesion during the operation and assist the normal operation. Compared with the chest and abdominal cavities, the pharyngeal cavity where esophageal cancer is located is smaller, and the space for doctors to operate is also smaller. In the process of using laparoscope to find lesions, it is easy to cause unnecessary harm to patients due to operational errors, affecting the effect of the operation. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a fluorescent laparoscope for clinical surgery of esophageal cancer, which can locally fix the laparoscope during the process of using the laparoscope to find lesions, thereby reducing the range of movement of the laparoscope, making it less likely to cause unnecessary harm to the patient due to operational errors and less likely to affect the surgical effect.

[0007] 2. Technical solution

[0008] To solve the above problems, the present invention adopts the following technical solutions.

[0009] A fluorescent laparoscope for clinical surgery of esophageal cancer comprises an auxiliary block, wherein a pair of operation holes and a laparoscope hole are bored on the auxiliary block, a laparoscope body is inserted in the laparoscope hole, a locking rubber block is fixedly connected to the outer wall of the laparoscope body, the lower end of the locking rubber block is inclined, and the inclined surface is low outside and high inside, an elastic cavity is bored in the locking rubber block, and a plurality of filling balls are filled in the elastic cavity, and the outer sides of the plurality of filling balls are fixedly connected to filling fiber clusters, and the adjacent filling balls are fixed together by winding the filling fiber clusters together, and a limited position slide groove is bored on the side wall of the laparoscope body, and the A locking plate is slidably connected in the limiting slide groove, and one end of the locking plate away from the limiting slide groove is located at the upper end of the locking rubber block. A limiting slide rod is fixedly connected to the inner wall of the limiting slide groove, and the limiting slide rod passes through the locking plate. A compression spring is sleeved on the outer side of the limiting slide rod, and the two ends of the compression spring are respectively fixedly connected to the inner wall of the limiting slide groove and the locking plate, and the compression spring is located on the upper side of the locking plate. It can be achieved by locally fixing the laparoscope in the process of using the laparoscope to find lesions, reducing the range of movement of the laparoscope, and not easily causing unnecessary harm to patients due to operational errors, and not easily affecting the surgical effect.

[0010] Furthermore, a reinforcing net matching the elastic cavity is embedded in the locking rubber block, and the reinforcing net is fixedly connected to the elastic cavity, thereby increasing the overall strength of the locking rubber block and preventing the locking rubber block from breaking during frequent deformation.

[0011] Furthermore, the aperture of the reinforcing net is much smaller than the size of the filling ball, so that even if cracks appear in the locking rubber block, leakage of the filling ball is unlikely to occur.

[0012] Furthermore, one end of the filling fiber cluster close to the inner wall of the elastic cavity passes through the locking rubber block and is fixedly connected to the reinforcing net, thereby increasing the ability of the filling ball to maintain a relative position without affecting the overall deformation ability of the locking rubber block, making it less likely for the filling ball to collapse structurally under the action of external force and less likely to affect the fixing effect of the locking plate.

[0013] Furthermore, a capture blanket is fixedly connected to the outer side of the reinforcing net, and one end of the capture blanket away from the reinforcing net passes through the locking rubber block and extends to the outer side of the reinforcing net. Anti-slip grooves are engraved on the locking plate to increase the friction between the locking rubber block and the locking plate, making it less likely for the locking rubber block and the locking plate to slip.

[0014] Furthermore, a wear-resistant ring is connected between the limit slide rod and the locking plate, and the wear-resistant ring is fixedly connected to the limit slide rod, thereby reducing the wear between the limit slide rod and the locking plate, so that the connection between the limit slide rod and the locking plate is not prone to shaking.

[0015] Furthermore, the portion of the capture blanket located outside the locking rubber block includes a capture hose, which is in a three-dimensional spiral shape. Adjacent capture hoses are intertwined to form a spatial three-dimensional structure, thereby increasing the elasticity of the portion of the capture blanket located outside the locking rubber block, so that the capture hose is not easily crushed by the locking plate and the three-dimensional structure is not easily collapsed. At the same time, the capture blanket forming the three-dimensional structure also has a capture function, and can effectively capture instrument fragments generated by the collision between the laparoscope hole and the laparoscope body during the operation, making them less likely to enter the patient's body and cause adverse reactions in the patient.

[0016] Furthermore, a plurality of elastic fibers are fixedly connected to the inner wall of the capture hose, and the plurality of elastic fibers are interlaced to form a three-dimensional spatial structure, thereby increasing the overall elasticity of the capture hose and making the spatial structure of the capture hose less prone to collapse.

[0017] Furthermore, a plurality of capillary pores are bored on the outer wall of the capture hose, and the plurality of capillary pores all penetrate the capture hose. The three-dimensional spatial structure formed between adjacent elastic fibers is filled with liquid glue. When the instrument fragments hit the elastic fibers, the liquid glue can be squeezed out, and the instrument fragments can be adhered to the elastic fibers, thereby increasing the capture effect of the elastic fibers.

[0018] Furthermore, the liquid glue is made of a substance that is harmless to the human body, preferably a starch solution, which is less likely to cause adverse reactions in patients due to leakage of the liquid glue.

[0019] 3. Beneficial effects

[0020] Compared with the prior art, the advantages of the present invention are:

[0021] In the present solution, in the process of inserting the laparoscope body into the laparoscope hole, the locking rubber block is compacted by the locking plate to achieve local fixation of the locking rubber block, thereby reducing the movable range of the laparoscope body. When the medical staff operates the laparoscope body, when the front end of the laparoscope body rotates in the same plane, the locking plate will not release the lock on the locking rubber block. In the process of using the laparoscope to find lesions, the laparoscope can be partially fixed to reduce the range of movement of the laparoscope. It is not easy to cause unnecessary harm to the patient due to operational errors, and it is not easy to affect the surgical effect. When the laparoscope body needs to be removed, it is only necessary to pull the laparoscope body upwards to remove the locking rubber block from under the locking plate. In this process, in order to save effort, the laparoscope body needs to be pulled out in a direction perpendicular to the auxiliary block, which can effectively avoid secondary harm to the patient caused by the laparoscope body during the removal process.

[0022] At the same time, the capture blanket can increase the friction between the locking rubber block and the locking plate, thereby increasing the fixing effect. On the other hand, the capture blanket can also effectively capture instrument fragments, which is not likely to cause secondary damage to the patient. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiment 1:

[0035] See also Figure 1-4 A fluorescent laparoscope for clinical surgery of esophageal cancer comprises an auxiliary block 1, a pair of operation holes 2 and a laparoscope hole 3 are drilled on the auxiliary block 1, the two operation holes 2 are used to install and plug surgical forceps, a laparoscope body 4 is inserted in the laparoscope hole 3, a locking rubber block 5 is fixedly connected to the outer wall of the laparoscope body 4, the lower end of the locking rubber block 5 is an inclined surface, and the inclined surface is low outside and high inside, an elastic cavity 6 is drilled in the locking rubber block 5, and a plurality of filling balls 7 are filled in the elastic cavity 6, and the outer sides of the plurality of filling balls 7 are fixedly connected with filling fiber clusters 8, and the adjacent filling balls 7 are connected by filling fibers. The fiber clusters 8 are twisted together to achieve fixation, and a limiting groove 11 is opened on the side wall of the laparoscope body 4. A locking plate 13 is slidably connected in the limiting groove 11. The end of the locking plate 13 away from the limiting groove 11 is located at the upper end of the locking rubber block 5. A limiting slide rod 12 is fixedly connected to the inner wall of the limiting groove 11. The limiting slide rod 12 passes through the locking plate 13. A compression spring 14 is sleeved on the outer side of the limiting slide rod 12. The two ends of the compression spring 14 are respectively fixedly connected to the inner wall of the limiting groove 11 and the locking plate 13, and the compression spring 14 is located on the upper side of the locking plate 13.

[0036] In this solution, when the laparoscope body 4 is inserted into the laparoscope hole 3, when the elastic cavity 6 contacts the auxiliary block 1, the elastic cavity 6 will quickly extend outwards to form a Figure 2In the state shown, the operation hole 2 will extend into the lower side of the locking plate 13. As the length of the part where the laparoscope body 4 is inserted into the laparoscope hole 3 increases, the part where the locking rubber block 5 extends to the periphery also gradually increases. The locking plate 13 is lifted, and the locking rubber block 5 is compacted by the locking plate 13 to achieve local fixation of the locking rubber block 5, thereby reducing the movable range of the laparoscope body 4. When the medical staff operates the laparoscope body 4, when the front end of the laparoscope body 4 rotates in the same plane, the locking plate 13 will not release the locking of the locking rubber block 5. It can be achieved by partially fixing the laparoscope in the process of using the laparoscope to find the lesion, reducing the range of the laparoscope's movement, and not easily causing unnecessary harm to the patient due to operational errors, and not easily affecting the surgical effect. When the laparoscope body 4 needs to be removed, it is only necessary to pull the laparoscope body 4 upward to remove the locking rubber block 5 from the bottom of the locking plate 13. In this process, in order to save effort, the laparoscope body 4 needs to be pulled out in a direction perpendicular to the auxiliary block 1, which can effectively avoid secondary damage to the patient caused by the laparoscope body 4 during the removal process.

[0037] See also Figure 3-6 A reinforcing net 9 matching the elastic cavity 6 is embedded in the locking rubber block 5. The reinforcing net 9 is fixedly connected to the elastic cavity 6 to increase the overall strength of the locking rubber block 5, so that the locking rubber block 5 is not easily broken during frequent deformation. The aperture of the reinforcing net 9 is much smaller than the size of the filling ball 7. Even if the locking rubber block 5 is cracked, it is not easy for the filling ball 7 to leak. One end of the filling fiber cluster 8 close to the inner wall of the elastic cavity 6 penetrates the locking rubber block 5 and is fixedly connected to the reinforcing net 9. Without affecting the overall deformation ability of the locking rubber block 5, the ability of the filling ball 7 to maintain a relative position is increased, so that the filling ball 7 is not easy to be knotted under the action of external force. The phenomenon of structural collapse is not easy to affect the fixing effect of the locking plate 13. The outer side of the reinforcing net 9 is fixedly connected with a capture blanket 10. The end of the capture blanket 10 away from the reinforcing net 9 passes through the locking rubber block 5 and extends to the outer side of the reinforcing net 9. The locking plate 13 is engraved with anti-slip patterns to increase the friction between the locking rubber block 5 and the locking plate 13, so that the locking rubber block 5 and the locking plate 13 are not easy to slip. A wear-resistant ring is connected between the limit slide bar 12 and the locking plate 13. The wear-resistant ring is fixedly connected to the limit slide bar 12, so as to reduce the wear between the limit slide bar 12 and the locking plate 13, so that the connection between the limit slide bar 12 and the locking plate 13 is not easy to shake.

[0038] The portion of the capture blanket 10 located outside the locking rubber block 5 includes a capture hose 1001, which is in a three-dimensional spiral shape. Adjacent capture hoses 1001 are intertwined to form a three-dimensional spatial structure, which increases the elasticity of the portion of the capture blanket 10 located outside the locking rubber block 5, so that the capture hose 1001 is not easily crushed by the locking plate 13, and is not likely to cause the collapse of the three-dimensional spatial structure. At the same time, the capture blanket 10 forming a three-dimensional spatial structure also has a capture function, which can effectively capture instrument fragments generated by the collision between the laparoscope hole 3 and the laparoscope body 4 during the operation, making it difficult for the fragments to enter the patient's body and cause adverse reactions to the patient. The inner wall of the capture hose 1001 is fixedly connected with a plurality of elastic fibers 1002, and the plurality of elastic fibers 1002 are intertwined to form a three-dimensional spatial structure. The structure increases the overall elasticity of the capture hose 1001, so that the spatial structure of the capture hose 1001 is not easy to collapse. A plurality of capillary pores 1003 are drilled on the outer wall of the capture hose 1001, and the plurality of capillary pores 1003 all penetrate the capture hose 1001. The capillary pores 1003 are located in the upper half of the locking rubber block 5, that is, the side that the locking plate 13 cannot press. The three-dimensional spatial structure formed between adjacent elastic fibers 1002 is filled with liquid glue. When the instrument fragments hit the elastic fiber 1002, the liquid glue can be squeezed out and the instrument fragments can be adhered to the elastic fiber 1002, thereby increasing the capture effect of the elastic fiber 1002. The liquid glue is made of a substance that is harmless to the human body, preferably a starch solution, which is not easy to cause adverse reactions in patients due to leakage of the liquid glue.

[0039] In this solution, during the process of inserting the laparoscope body 4 into the laparoscope hole 3, the locking rubber block 5 is compacted by the locking plate 13 to partially fix the locking rubber block 5, thereby reducing the movable range of the laparoscope body 4. When the medical staff operates the laparoscope body 4, when the front end of the laparoscope body 4 rotates in the same plane, the locking plate 13 will not release the locking of the locking rubber block 5. It can be achieved that in the process of using the laparoscope to find the lesion, the laparoscope is partially fixed, the range of the laparoscope can be reduced, and it is not easy to cause unnecessary harm to the patient due to operational errors, and it is not easy to affect the operation. The effect is achieved, and when the laparoscope body 4 needs to be taken out, it is only necessary to pull the laparoscope body 4 upwards, so that the locking rubber block 5 can be pulled out from under the locking plate 13. In this process, in order to save effort, the laparoscope body 4 needs to be pulled out in a direction perpendicular to the auxiliary block 1, which can effectively avoid secondary damage to the patient caused by the laparoscope body 4 during the removal process. At the same time, the setting of the capture blanket 10 can increase the friction between the locking rubber block 5 and the locking plate 13 and increase the fixing effect. On the other hand, the capture blanket 10 can also effectively capture instrument fragments, which is not easy to cause secondary damage to the patient.

[0040] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
