Description

Technical Field

[0001] The present invention relates to the technical field of electronic imaging, and in particular to a laparoscope structure. Background Art

[0002] With the development of electronic technology, miniaturization and high definition of electronic imaging technology have become possible. These technologies have made the use and promotion of electronic laparoscopes possible. Currently, various 2D and 3D electronic laparoscopes have been widely used in major hospitals.

[0003] The existing electronic laparoscope has a complex structure, is difficult to maintain, and has varying electronic anti-interference capabilities. Unsatisfactory electronic anti-interference directly affects the normal progress of the operation and threatens the patient's life.

[0004] The unstable and loose structure of the mirror body will lead to a decrease in the sealing performance of the mirror body. The fluid outside the mirror body structure will leak into the inside of the mirror body through the installation gap, such as alcohol used in the disinfection process, body fluids during use, and washing liquids during cleaning. Therefore, the stable structure of the mirror body can ensure better sealing performance.

[0005] As the core component of the electronic laparoscope, the scope body is in direct contact with the human body during use, so the stability, sealing and anti-electromagnetic interference of the scope body structure are crucial. Summary of the invention

[0006] Purpose of the invention: In view of the above-mentioned deficiencies, the present invention proposes a laparoscope structure, which achieves the effects of stable structure, reliable sealing and easy disassembly by reducing the structural parts of the scope.

[0007] Technical solution:

[0008] A laparoscope structure comprises a lens, a handle for holding and operation, and a sheath tube between the two for passing an illuminating optical fiber and a cable. The illuminating optical fiber passes through the handle and extends to the sheath tube. The handle comprises a core bracket and a shell that cooperates with the core bracket to achieve a sealed installation. The core bracket comprises two arcuate rods with their length directions as axes and installed in accordance with the shape of the shell, and mounting parts at the front and rear ends of the core bracket that cooperate with the shell to achieve a sealed installation. The circuit board in the handle is installed in the space surrounded by the two arcuate rods.

[0009] The mounting parts at the front and rear ends of the core support are respectively a front support and a rear cover which are coaxially arranged and hollow.

[0010] The core support is of integrated design.

[0011] The shell is a cylindrical structure and is sleeved outside the core bracket.

[0012] A hollow head seal is installed at the front end of the shell, and the inner wall and outer wall of the head seal are respectively sealed with the front end bracket at the front end of the core bracket and the inner wall of the shell.

[0013] A guide groove for slidingly installing the arc surface rod is provided in the shell at a position corresponding to at least one side edge of the arc surface rod, and the guide groove guides the core bracket to be slidably installed in the shell.

[0014] The guide groove limits the core support in the radial direction of the shell.

[0015] A slot is provided on the shell body, in which a key box is installed; support members for supporting the key box are respectively provided at the front and rear ends of the slot.

[0016] The support member comprises a fixed block fixed on the shell and a pressing block movably mounted on the fixed block, and the pressing block is a wedge-shaped block with a tip facing the key box.

[0017] A carrier extending toward the key box is arranged at the lower end of the fixing block facing the key box, and the pressing block is mounted on the carrier; an adjusting screw is installed on the fixing block at the position of the carrier, and the end of the adjusting screw abuts against the pressing block.

[0018] Baffles for blocking the pressing block from moving toward both sides are respectively arranged on both sides of the carrier.

[0019] The lens includes:

[0020] A lens holder, a binocular lens is fixedly mounted on the front end thereof;

[0021] A support seat, wherein a matching groove having the same shape as the front end of the lens seat is provided in the middle thereof, and support grooves having the same shape as the lighting optical fiber are provided on both sides thereof;

[0022] The lens seat is plug-fitted with the support seat.

[0023] A lens protection cover and an optical fiber protection cover are respectively bonded to the end surface of the support seat at the positions of the matching groove and the support groove.

[0024] The lens seat and the support seat are complementary in shape, and a groove is formed at the rear end of the lens seat, and the lens seat and the support seat are plugged together to form a space covering the lens circuit board installed therein.

[0025] Beneficial effects:

[0026] 1. The present invention adopts a structure in which the core structural member and the shell structural member are installed separately, and the core structural member and the shell structural member are respectively regarded as a whole, and then the two parts are combined into a mirror body, so that the assembly and maintenance of the structural members are convenient.

[0027] 2. The present invention adopts a structure in which the core structural member and the shell structural member are installed separately. The core structural member adopts an integral member to ensure that the front and rear ends thereof are installed coaxially. During the coordinated installation, it is avoided that the front and rear ends of the core structural member are not coaxial due to assembly problems, resulting in poor sealing effect between the shell structural member and the core structural member.

[0028] 3. The arc inner cavity structure designed in the present invention cooperates with the shape of the handle shell to thicken the middle position to the maximum extent to increase strength and rigidity, effectively avoiding the thin-walled position caused by disassembly in the prior art and improving the overall strength.

[0029] 4. The key box support structure designed in the present invention can not only realize stable vertical support, but also can be adaptively adjusted after long-term use to ensure stable installation of the key box without affecting key operation.

[0030] 5. The lens end protection of the present invention adopts a separate structure, that is, the lighting window protection and the lens protection are protected separately, and there is no direct contact between the two, which prevents cross-light and improves imaging quality.

[0048] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments.

[0049] Figure 1 FIG. 1 is a schematic diagram of the structure of the laparoscope of the present invention, as shown in FIG. Figure 1 As shown, the laparoscope of the present invention comprises a lens assembly 1, a handle assembly 3 for holding operation, and a sheath 2 between the lens assembly 1 and the handle assembly 3 for illuminating optical fiber 15 and cables between the lens assembly 1 and the handle assembly 3, as shown in FIG. Figure 2 As shown, there are two illumination optical fibers 15 passing through the sheath tube 2, and they are symmetrically arranged in the sheath tube 2; the circuit board in the handle assembly 3 is connected to the external cable 4 to realize power supply and information transmission.

[0050] like Figure 2 As shown, the lens assembly 1 includes a lens PCB 18 connected to a cable passing through the sheath tube 2, a lens seat 17 for mounting a binocular lens 14, and a lens housing 13 for protection. The front end of the lens housing 13 is open, and the rear end thereof cooperates with the step at the end of the sheath tube 2 to realize the installation of the lens assembly 1. The inner and outer diameters of the lens housing 13 are consistent with the inner and outer diameters of the sheath tube 2; Figure 2 , 3 As shown, the lens seat 17 is inserted into the support seat 16. The lens seat 17 is designed as a hollow cylindrical structure with an outer diameter smaller than the inner diameter of the sheath tube 2. The portion corresponding to the illumination optical fiber 15 is cut off to pass the illumination optical fiber 15. The binocular lens 14 is fixedly mounted on the front end of the lens seat 17 and extends to the front end of the support seat 16. The diameter of the front end of the lens seat 17 is smaller than the diameter of the rear end of the lens seat 17. The lens PCB 18 is arranged in the hollow structure at the rear end of the lens seat 17. Figure 3 The outer diameter of the support seat 16 is slightly smaller than the inner diameter of the sheath tube 2, and a matching groove 161 consistent with the shape of the front end of the lens seat 17 is opened in the middle thereof, and a supporting groove 162 consistent with the shape of the lighting optical fiber 15 is provided at a position corresponding to the lighting optical fiber 15. The support seat 16 is sleeved on the outside of the front end of the lens seat 17 through the matching groove 161 in the middle thereof, and the lighting optical fiber 15 is passed through the supporting groove 162 of the support seat 16.

[0051] Furthermore, in the present invention, the support groove 162 of the support seat 16 can be designed to extend along the axial direction to a set length, which is less than or equal to the axial length of the lens seat 17. Then, the structure formed by the extension is just complementary to the cut-off portion at the rear end of the lens seat 17, thereby forming a complete covering space to further protect the lens PCB 18 installed in the hollow structure at the rear end of the lens seat 17. Figure 3 shown.

[0052] In the present invention, the support seat 16 and the lens seat 17 are both made of non-metallic materials, such as PEEK, ABS, etc., which can completely isolate the lens imaging electronic components from the external metal tubes and metal parts, thereby effectively avoiding the problem that external discharge will reduce the stability of the head end lens imaging signal. In addition, the present invention uses adhesive glue to fix the relative position between the parts, fills all gaps with electronic insulating glue after installation, and partially applies insulating three-proof paint to the lens PCB18, so that the entire module is wrapped by non-metal, insulating glue, and insulating three-proof paint, and complete signal isolation from external metal parts is achieved.

[0053] A first mounting groove 131 and a second mounting groove 132 are provided at the front end opening of the lens housing 13, and the shapes of the first mounting groove 131 and the second mounting groove 132 are respectively consistent with the matching groove 161 and the supporting groove 162 on the supporting seat 16, and are respectively used to install the lens protection cover 11 and the optical fiber protection cover 12 for protecting the binocular lens 14 and the illumination optical fiber 15, thereby solving the problem in the prior art that the front end protection cover adopts a circular integral structure, and the illumination optical fiber optical path interferes with the camera imaging optical path, thereby increasing the camera stray light.

[0054] In the present invention, the lens protection cover 11 and the optical fiber protection cover 12 are made of glass of corresponding shapes, and both are installed at corresponding positions by glue.

[0055] Furthermore, the lens protective cover 11 is installed in the first installation groove 131 by gluing, so as to be installed in front of the binocular lens; and the optical fiber protective cover 12 is fixedly installed in the second installation groove 132 of the lens housing 13 by gluing; after the lens protective cover 11 and the optical fiber protective cover 12 are bonded, the support seat 16 and the lens seat 17 are inserted into the lens housing 13, and then fixed by gluing. In the present invention, the protection cover (glass in the present invention) of the binocular lens 14 and the illumination optical fiber 15 is installed separately, so that the isolation of the optical path is achieved, thereby reducing the stray light of the camera.

[0056] Furthermore, the lighting window (i.e., lighting optical fiber 15) protective glass and the imaging lens (i.e., binocular lens 14) protective glass have different requirements for glass transmittance. The imaging lens protective glass has higher requirements for glass transmittance. The protective glass of the present invention uses sapphire glass to prevent the lens from being scratched. The lighting window protective glass uses ordinary sapphire glass, and the imaging lens protective glass uses coated sapphire glass. The glass is coated on both sides to ensure that the optical transmittance of the coated glass exceeds 95%.

[0057] Figure 4 is an exploded schematic diagram of the handle assembly, such as Figure 1 , 4 As shown, the handle assembly 3 includes a handle body 31 and a button box 32 mounted on the handle body 31. An indicator light 33 for indicating the working state of the laparoscope body is also provided on the handle body 31. Both the button box 32 and the indicator light 33 are connected to the circuit board in the handle body 31 through cables. A tail harness 34 for binding an external cable connected to the circuit board in the handle assembly 3 is also provided at the rear end of the handle body 31. In the present invention, the indicator light 33 can be installed on the button box 32.

[0058] Reference Figure 4 The handle body 31 includes a handle housing 315 and a core bracket 316 which are mounted in cooperation with each other. Fig. 9As shown, the core bracket 316 includes a bracket body 3162, a front bracket 3161 arranged at the front end of the bracket body 3162, and a rear cover 3164 arranged at the rear end of the bracket body 3162. The bracket body 3162 is formed by two arc rods that are mutually symmetrical and coaxial along its length direction, and the arc of the arc rod is generally less than 60°, and its length is generally designed to be greater than the length of the handle PCB 317 in the handle assembly 3; the space surrounded by the two arc rods is used to accommodate the handle PCB 317, and the handle PCB 317 is connected to the external cable 4; the front bracket 3161 is designed as a hollow cylindrical structure, and the rear cover 3164 is also designed as a circle. The two are coaxially arranged to ensure the sealing effect. A plurality of support members 3163 are arranged at the same horizontal position on the inner side of the two arc rods, and threaded holes are provided on them. The handle PCB 317 is placed on the support members 3163 and fixed by screws. In the present invention, the core of the handle as a whole is mainly subjected to the bending moment force caused by the front end sheath 2, and its weak link is the middle position of the handle. The arc inner cavity structure designed and formed by the present invention cooperates with the shape of the handle shell 315 to maximally thicken the middle position of the handle to increase strength and rigidity.

[0059] Furthermore, the front bracket 3161, the bracket body 3162 and the rear cover 3164 adopt an integrated design, which can effectively avoid thin-walled locations caused by disassembly and improve the overall strength.

[0060] Reference Figure 4 , 5 The handle housing 315 is a cylindrical structure, which is sleeved outside the core bracket 316. In its internal space, two symmetrical areas are formed except the area where the core bracket 316 is located, which are used to install the lighting optical fiber 15; the rear cover 3164 is a step-type structure, and a sealing groove is designed on the outer wall of the step, and a third sealing ring 318 is arranged inside the groove. The inner wall of the rear end of the handle housing 315 is sealed by cooperating with the third sealing ring 318 in the sealing groove; a hollow head seal 312 is installed at the front end of the handle housing 315, and the head seal 3 12 is also designed as a step-type structure, and sealing grooves are designed on its inner side wall and the outer side wall at the step, and the corresponding sealing grooves are respectively provided with a second sealing ring 314 and a first sealing ring 313. The head seal 312 cooperates with the inner wall of the handle housing 315 through the first sealing ring 313 in the sealing groove of its outer side wall to achieve sealing installation. At the same time, the head seal 312 cooperates with the front end bracket 3161 of the core bracket 316 through the second sealing ring 314 in the sealing groove of its inner wall to achieve further sealing installation and axial fixation. The coaxiality of the front end bracket 3161 of the core bracket 316 and the rear cover 3164 ensures the coaxial installation of the first sealing ring, the second sealing ring, and the third sealing ring to ensure the sealing effect.

[0061] Furthermore, a plurality of screw holes are provided on the head seal 312 , and threaded holes are opened at corresponding positions on the end surface of the core bracket 316 . After the head seal 312 is installed, axial fixation can be further achieved by screws.

[0062] Furthermore, if Fig.10 As shown, in another embodiment of the present invention, the inner diameter of the handle shell 315 is smaller than the maximum radial width of the core bracket 316, and a guide groove consistent with its shape is provided at the corresponding positions of the inner wall and the two arc rods of the bracket body 3162. The arc diameter and arc width of the guide groove are the same as the arc diameter and arc width of the arc rod, and the two form a high-precision matching surface; during installation, the handle shell 315 can be installed through the guide groove therein and the matching installation of the two arc rods of the bracket body 3162, which can not only realize rapid positioning and installation, but also realize radial fixation between the two to prevent relative rotation between the two.

[0063] In another embodiment of the present invention, the inner diameter of the handle housing 315 is consistent with the maximum width of the core bracket 316 in the radial direction, so that the core bracket 316 can be exactly inserted into the handle housing 315. The two arc rods of the core bracket 316 are symmetrical to each other, so the same side of the two arc rods is located on the same plane. In this embodiment, a guide groove for sliding installation of the arc rod is formed inwardly at a position corresponding to the same side of the two arc rods of the core bracket 316 in the handle housing 315, which is used for guiding the arc rod when the core bracket 316 is installed with the handle housing 315. Since the inner diameter of the handle housing 315 is consistent with the maximum width of the core bracket 316 in the radial direction, the two arc rods can only be installed with the handle housing 315 along the guide groove, thereby limiting the relative rotation between the core bracket 316 and the handle housing 315, that is, limiting its rotation in the radial direction.

[0064] A hollow cover 311 is also installed at the front end of the head seal 12. A step is provided on the outer side wall of the front end of the handle shell 315. The hollow cover 311 is installed at the front end of the handle shell 315 by cooperating with the step.

[0065] Reference Figure 4 , 8 9. Two mounting holes are provided on the rear cover 3164 of the core bracket 316, one of which is used to pass the cable 4, and the other is used to install the lighting optical fiber 15. The harness mounting part 34 is installed in the mounting hole for passing the cable 4. The harness mounting part 34 is also a hollow structure with an outer diameter smaller than the diameter of the mounting hole. A step with a diameter larger than the diameter of the mounting hole is provided at its front end, and its outer diameter gradually decreases to its rear end. The cable 4 is passed through the harness mounting part 34. After the harness mounting part 34 is installed in the mounting hole, its front end is fixed and installed by a hollow fixing part 319 with screws.

[0066] Reference Figure 5 , 8 A slot is provided on the handle housing 315, in which a key box 32 is installed. The key box 32 is subjected to a force perpendicular to the keys during use, so a vertical support is required to ensure long-term use. Therefore, the present invention provides front and rear support members at the front and rear ends of the slot, respectively. Figure 6 As shown, the front end support member includes a front end fixing block 321 fixed to the handle housing 315 and a front end pressing block 323 movably mounted on the front end fixing block 321 through a front end pressing screw 322. Fig.10 As shown, a mounting plate 3151 is formed in the handle housing 315 along a radial extension, and a front end fixing block 321 is fixedly mounted on the mounting plate by screws, and a carrier extending toward the key box 32 is provided at the lower end of the front end fixing block 321, and a front end clamping block 323 is mounted on the carrier, which is a wedge-shaped block with the tip facing the key box 32, and a screw hole is provided on the front end fixing block 321, and the front end clamping screw 322 passes through the screw hole and abuts against the end surface of the front end clamping block 323 facing away from the key box 32 to achieve position adjustment of the front end clamping block 323; similarly, the rear end support member structure is similar to the front end support member, including a rear end fixing block 324 fixed to the handle housing 315 and a rear end clamping block 326 movably mounted on the rear end fixing block 324 by the rear end clamping screw 325, and the mounting method is consistent with the front end support member.

[0067] In a specific embodiment of the present invention, Figure 6 , 7 As shown, baffles are respectively provided on both sides of the bearing body on the front and rear end fixing blocks to block the corresponding front and rear end pressing blocks from moving to both sides.

[0068] Furthermore, the baffle and the carrier are an integrated structure.

[0069] Furthermore, the front and rear end clamping blocks are provided with steps at one end close to the corresponding fixing block, so as to limit the movement of the clamping blocks and prevent the clamping blocks from going too deep and detaching from the carrier.

[0070] In the present invention, the carrier at the lower end of the front fixing block 321 or the rear fixing block 324 can be designed as a whole, and its width can be consistent with the width of the corresponding fixing block, or it can be inconsistent with the width of the corresponding fixing block; further, the carrier at the lower end of each fixing block can also be designed as multiple, such as at the front end of the key box 32, because it is necessary to avoid the connection cable and other structures of the key box 32, multiple smaller-sized carriers can be designed, such as Figure 6 , there are 2, and at the rear end of the key box 32, there is enough space and a larger carrier can be used.

[0071] In the present invention, a wedge block is used to install the key box to achieve stable vertical support, and the installation error can be adjusted by adjusting the support length of the wedge block on the key box; and because the key box 32 is pressed perpendicular to the force of the key, it will inevitably cause impact and wear on its supporting parts, so after a period of use, the support of the key box 32 may be insufficiently stable. The present invention can adjust the wear gap of the wedge block to adapt to the key box 32 to ensure that the installation of the key box 32 is stable and will not affect the key operation.

[0072] The handle body 31 of the present invention adopts a modular design of a handle shell 315 and a core support 316, which can solve the problems of complex handle structure and difficult maintenance, assembly and disassembly in existing laparoscopes.

[0073] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various equivalent transformations (such as quantity, shape, position, etc.) can be made to the technical scheme of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
