Referring to fig. 1 and 2, the endo-surgical illumination device may include: a housing 1 and a light source system 2 accommodated in the housing 1. Referring to fig. 3 in combination, the light source system 2 may include: a base 21, and a light source circuit and a switching circuit arranged on the base 21; the light source circuit comprises a power supply 22 and a light source 23 connected together; the switching circuit comprises a control switch 24 having a voltage limiting and current limiting module 240, the control switch 24 being adapted to: the light source circuit is controlled to be conducted to turn on the light source 23, and the light emitting intensity of the light source 23 is reduced to reach the acceptable light emitting intensity threshold in the human body through the voltage limiting and current limiting module 240.
The light-emitting intensity threshold acceptable in the human body can refer to the minimum light-emitting intensity extremum or extremum range which can be born by the internal organs of the human body, the internal organs of the human body can not be burnt below the light-emitting intensity threshold, and the internal organs of the human body have the risk of being burnt when exceeding the light-emitting intensity threshold. Therefore, the reasonable control of the luminous intensity of the light source 23 is a necessary factor for the internal surgical illumination device of the present technical solution to be placed inside the human body.
The light source system 2 is housed within the housing 1, maintaining structural integrity and reliability. In operation, the casing 1 is put into a human body, and the control switch 24 is operated to turn on the light source circuit so as to turn on the light source 23, and the light source 23 can provide proper luminous intensity to meet the illumination requirement.
To protect the internal organs of the human body, the light source 23 may include a cold light source. The cold light source can not generate infrared rays, and the damage to organs caused by infrared irradiation to human bodies can be avoided. The cold light source can comprise an LED lamp, the luminous color of the LED lamp is pure, white light with stable light emission can be generated, and the energy is saved and the service life is long.
For the purpose of achieving a small size of the built-in surgical illumination device, the base 21 may include a semiconductor sheet, and the light source circuit and the switching circuit may be integrated circuits integrated in the semiconductor sheet. The base 21 may be selected from semiconductor sheets, and the light source circuit and the switching circuit are integrated circuits formed on the surface of the semiconductor sheets using a semiconductor process. The integrated circuit has the characteristic of miniaturization, and the size of the base 21 can be greatly reduced, so that the technical scheme provides a design thought of the integrated circuit and can realize the expectation of reducing the size of the light source system 2.

The control switch 24 may include: a first switch 241 for generating a first level signal;
A logic selection module 243 electrically connected to the first switch 241 for receiving the first level signal to generate a second level signal;
a second switch 242 connected to the switch circuit and electrically connected to the logic selection module 243, for receiving the second level signal to turn on the light source circuit;
The voltage-limiting and current-limiting module 240 is disposed between the logic selection module 243 and the second switch 242, and the voltage-limiting and current-limiting module 240 is adapted to reduce the second level signal to increase the power-on resistance of the second switch 242, so as to achieve the purpose of voltage-limiting and current-limiting the light source 23.
The first switch 241 functions as a trigger, and the first level signal may be a low level or a high level as a trigger signal for turning on the light source 23. The trigger signal may trigger the logic selection module 243 to generate a second level signal, thereby enabling the second switch 242 to form a path.

The first switch 241 is adapted to: the pressing portion 244 is pressed to bring the movable contact 24b and the stationary contact 24a into contact to generate a first level signal. When the light source system 2 is placed in the accommodating chamber 1a, the pressing portion 244 may be disposed opposite to the second bottom wall 112 of the first portion 11, so that the pressing portion 244 may be easily pressed across the second bottom wall 112 to activate the light source 23, which is convenient to operate.
The second switch 242 may be a triode switch including a base B, a collector C, and an emitter E; the base B is connected with a logic selection module 243, and the collector C and the emitter E are connected with a light source circuit. The second switch 242 shown in fig. 5 is an NPN-type triode switch, so that when the second level signal is at a high level, the triode switch can be turned on, the collector C and the emitter E are turned on, the light source circuit is turned on, and the power supply 23 is turned on. Conversely, in an alternative solution, when the second switch selects the PNP transistor switch, and the second level signal is at a low level, the transistor switch may be turned on, so that the power supply is turned on.
The voltage limiting and current limiting module 240 can reduce the second level signal, so that the openable channel region of the triode switch is narrow, and the resistance of the triode switch is larger, thereby reducing the power of the light source 23 and finally achieving the purpose of reducing the luminous intensity.
The voltage limiting and current limiting module 240 may select a resistor to consume power to reduce the second level signal.
The light source system 2 may further include: the housing 25, the housing 25 defines a housing portion 25a, and the base 21, the light source circuit, and the switching circuit can be housed in the housing portion 25a, and the housing 25 has a transparent structure. Thus, the light source system forms an integrated module, and the housing 25 including the base 21, the light source circuit, and the switching circuit is housed in the housing chamber 1a at the time of assembly. The housing 25 is transparent, allowing the light source 23 to emit light outwards for illumination purposes.
The housing 25 may include:
The body portion 250 including an annular side wall (hereinafter referred to as a first side wall) 251, a bottom wall (hereinafter referred to as a first bottom wall) 252 at one axial end of the first side wall 251, and a first opening 25b at the other axial end, the first bottom wall 252 being formed with a second opening 25c, the first side wall 251 and the first bottom wall 252 defining a receiving portion 25a;

The base 21 has a first surface 211 facing the second opening 25c, and at least the control switch 24 is arranged at the first surface 211 and facing the second opening 25c.
In this embodiment, the housing 25 includes two independent components, namely the body 250 and the cover 253, which is advantageous for product assembly and compact structure of the light source system 2.
To promote the feasibility of the endo-surgical illumination device, referring to fig. 1 and 2, the housing 1 may include:
A first portion 11 defining a receiving cavity 1a, the receiving cavity 1a being adapted to receive the light source system 2;
A second portion 12 coupled to the first portion 11, the second portion 12 defining an adsorption chamber 12a and having an adsorption port 12b communicating the adsorption chamber 12a with the outside;
In the housing 1, at least the first portion 11 has a transparent structure suitable for light emission, and the second portion 12 is suitable for being deformed by extrusion along the depth direction a of the adsorption cavity 12a to form negative pressure in the adsorption cavity 12 a.
In operation, the built-in operation lighting device with the shell 1 can be placed into a human body from an operation incision, the adsorption port 12b of the second part 12 is aligned with the human body inner membrane near the operation position, the second part 12 is extruded towards the human body inner membrane, the second part 12 is extruded and deformed to form negative pressure in the adsorption cavity 12a, and the shell 1 is adsorbed on the human body inner membrane. At this time, the light source system 2 is turned on, and the light is emitted through the second portion 12 to illuminate the operation area, thereby providing the art field. After the operation, the housing 1 can be slid along the human intima or the second portion 12 can be pressed so that air can enter the suction chamber 12a from the suction port 12b, the negative pressure in the suction chamber 12a can be eliminated, and then the built-in operation lighting device can be easily removed.
The adsorption characteristic of the shell 1 can realize that the built-in operation lighting device is placed in the inner cavity of a human body and keeps stable setting, provides stable and concentrated light, and illuminates local operation fields, so that dependence on shadowless lamps is reduced, and the operation progress is quickened. In particular to an operation of deep tissues of a human body, which has a deep operation view and can be blocked by internal organs of the human body, and the head of an operator can block the lamplight of a shadowless lamp. Therefore, the technical proposal provides a new idea of built-in operation illumination.
Moreover, this adsorption characteristic has no special requirements on the volume of the housing 1, and the volume of the housing 1 is made small to accommodate surgical illumination with a small surgical incision. In the operation, the shell 1 has smaller volume, no shadow is caused, the influence on the vision of a doctor is avoided, and the doctor can accurately position the operation part.
Particularly important, in the field hospital or battlefield operation, under the condition that the lighting equipment is insufficient or no lighting equipment is arranged on the battlefield (especially at night), the built-in operation lighting device has small volume and convenient carrying, and can well meet the operation requirements of soldiers. More importantly, in the operation, the built-in operation lighting device is placed in a human body, and light is not easy to expose, so that the built-in operation lighting device is not easy to expose to enemies, and has very important military and strategic effects.
The following illustrates the unexpected effect of the built-in operation lighting device according to the present invention.
In the current gastric cancer radical treatment operation, the tissue and blood vessels around the cardia need to be dissected, especially the separation is carried out between the fundus and the spleen, the part is positioned at the highest and deepest position of the abdominal cavity and is close to diaphragm, and the fundus and spleen of most patients are closely adhered, so that the shadowless lamp is difficult to obtain good illumination effect, spleen tearing, blood vessel injury and the like are very easy to occur during the operation, unnecessary massive hemorrhage in the operation is caused, even the hemostasis is impossible, the spleen resection needs to be combined, the operation is difficult to increase, and unnecessary injury is brought to the patients. To solve this problem, the housing 1 can be adsorbed on the peritoneum by using the built-in operation lighting device, and a concentrated and good lighting effect is provided for the deepest part of the abdominal cavity, which can reduce risks of spleen tearing and vascular injury and reduce operation difficulty.
In addition, for example, in the low-level rectal cancer operation, the pelvis of different patients is different in size, especially in male patients, the pelvis is narrow, or some patients have large and low tumors, the operation space reserved for operators is extremely limited, and even only one gap can be operated. At this time, the illumination of the shadowless lamp is often blocked by the head of the operator and cannot irradiate the operation field, so that the operator is almost in the dark operation, the operation difficulty is increased, the operation risk is greatly increased, the severe patient has sacral anterior hemorrhage, the male has prostate injury to cause hemorrhage, the female may have vaginal injury to cause rectocele, and the complications seriously endanger the life of the patient are all complications. To this problem, the built-in operation lighting device is small in size, can utilize shell 1 to adsorb on the pelvic cavity intima, provides concentrated and accurate illumination in narrow and small space, solves the problem that the operation degree of difficulty is big that the patient pelvis is less, or the operation space is narrow and small brings, reduces the operation risk, avoids the operation to endanger patient's life.
Besides being directly placed in a human body, the built-in operation lighting device of the technical scheme can be matched with built-in operation instruments for use. Referring to fig. 4, the surgical instrument may be a deep retractor 3, and the deep retractor 3 may include a hook portion 30, and the surgical illumination device may be attached to the hook portion 30.
In operation, the deep retractor 3 pulls the incision through the hook portion 30 to fully expose the surgical field for the surgeon to perform the operation. In this process, the built-in operation lighting device is absorbed on the hook part 30 through the shell 1 and goes deep into the human body, so as to achieve the purpose of lighting in operation. Depending on the size of the hook portion 30, two, one, or other number of endo-operative lighting devices may be disposed thereon. In addition to such deep draw hooks 3, other internal surgical instruments may include: an instrument body; the built-in operation lighting device is adsorbed on the instrument body through the shell. The built-in surgical instrument is a surgical instrument which can be inserted into a human body during operation.
Referring to fig. 1 and 2, the second portion 12 may include: a deformation section extending in the depth direction a, the inner diameter of the deformation section gradually increasing or decreasing in a direction facing the inside of the adsorption chamber 12a from the adsorption port 12b, where the gradually increasing or decreasing may be: in one direction a, the inner diameter of the deformation section is either gradually increasing or gradually decreasing, so that the deformation section has a truncated cone shape.
For example, along the depth direction a of the adsorption cavity 12a, the second portion 12 includes three deformation sections 121, 122, 123 connected in sequence, and the three deformation sections 121, 122, 123 are connected together to define the adsorption cavity 12a. Each deformation section is in a truncated cone shape, along the depth direction a of the adsorption cavity 12a, the deformation sections 121, 122 and 123 are extruded, deform towards the first part 11, and the axial length is gradually reduced so as to compress the space of the adsorption cavity 12a, and air in the adsorption cavity 12a is discharged to form negative pressure. Compared with the cylindrical shape, the deformation sections 121, 122 and 123 with the truncated cone shape are easier to deform, so that the application is easy, labor-saving and more convenient.
Along the depth direction a, an included angle is formed between two adjacent deformed sections, for example, an included angle α1 is formed between the deformed sections 121 and 122, and an included angle α2 is formed between the deformed section 122 and the deformed section 123. In this way, adjacent two deformed segments intersect to share one end. The location of the intersection provides a less stressed area where adjacent deformation segments are more likely to deform when the second portion 12 is compressed in the depth direction a, which reduces the difficulty of intraoperative installation.
In the depth direction a, deformation segments having an inner diameter gradually increasing and deformation segments having an inner diameter gradually decreasing are alternately arranged in a direction facing the inside of the adsorption chamber 12a from the adsorption port 12 b. For example, the inner diameter of the deformation section 121 gradually decreases in the direction from the suction port 12b toward the inside of the suction chamber 12a, the inner diameter of the deformation section 122 gradually increases, and the inner diameter of the deformation section 123 gradually decreases. The second portion 12 is thus bellows-like and when pressed in the depth direction a, all deformation sections fold together. In the structural form, all deformation sections can not interfere with each other during extrusion deformation, and deformation is very easy to occur at the intersection position.
Of these three deformed sections, the deformed section 121 defines the suction port 12b, and the inner diameter of the deformed section 121 gradually decreases from the suction port 12b toward the inside of the suction chamber 12a, and the deformed section 121 is horn-shaped, forming the suction port 12b as a horn-shaped mouth. When the suction port 12b is extruded, the suction port 12b with a larger caliber is more beneficial to exhausting air outwards, and the purpose of facilitating the installation in the operation is achieved.
In another modification of the present embodiment, the second portion 12 includes three deformation sections 121, 122, 123, where the deformation section may be a section, and the length along the depth direction is equal to the depth of the adsorption cavity, and the second portion may include only a section of deformation section. Or in another variation, referring to fig. 5, the deformed segment 120' may be two segments. Or the deformation section can be more than three sections. The greater number of deformed segments can define a larger volume of suction chamber, so that the more air is expelled under compression, the greater the suction force generated, and the better the stability of the installation of the endo-surgical illumination device.
For the housing 1, the material selected to achieve this deformation may be silicone, which is prone to elastic deformation.
Referring to fig. 1 and 2, for the housing 1, the adsorption chamber 12a communicates with the accommodation chamber 1a, so that the light source system 2 can be accommodated in the accommodation chamber 1a through the adsorption chamber 12a from the adsorption port 12b side. This promotes feasibility and convenience of product assembly.
The first portion 11 may include: an annular side wall (hereinafter referred to as a second side wall) 110; a top wall 111 and a bottom wall (hereinafter referred to as a second bottom wall) 112, which are located on both axial sides of the second side wall 110, are connected to the second side wall 110 so as to define the accommodation chamber 1a, wherein the top wall 111 is connected to the second portion 12. An opening 11a is formed in the top wall 111, and the opening is connected to the 11a adsorbing chamber 12 a. This forms a receiving cavity 1a having an opening 11a at one end, and the top wall 111 and the second bottom wall 112 cooperate to limit the light source system 2, effectively preventing the light source system 2 from being blown out of the opening.
In this case, the second side wall 110 and the second bottom wall 112 may each be a transparent structure, made of a transparent material. For example, such transparent material may be selected from silica gel. Thus, the possibility exists that the first portion 11 and the second portion 12 are integrally formed and may be made of transparent silicone.
In this case, the light source system 2 is placed into the accommodation chamber 1a of the housing 1 with the cover 253 facing the adsorption chamber 12a and the first bottom wall 252 of the body portion 250 facing the second bottom wall 112 of the housing 1. In this way, the control switch 24, in particular the first switch 241, is directly facing the second bottom wall 112 of the housing 1 through the second opening 25c, so that the first switch 241 can be pressed across the housing 1 to generate the first level signal.
The first surface 211 of the base 21 faces the second bottom wall 112 of the housing 1, and the second bottom wall 112 can protect the control circuit 24 from the humid environment inside the human body. Further, the cover 251 is disposed on the first opening 25b, so as to prevent liquids such as moisture from affecting normal operation of the light source circuit and the control circuit 24, and ensure stable operation of the light source system 2.
The power source 22 (refer to fig. 3) may be disposed on the first surface 211, and the second bottom wall 112 of the housing 1 may protect the power source 22.
