Description

[Technical Field]

[0001] The present invention relates to a surgical instrument, and more particularly to a sample receiving device for minimally invasive surgery. [Background technology]

[0002] Figures 1 and 2 show the sample bag described in Patent Document 1. This conventional sample bag is configured to have a sleeve tube 11, an operating lever 12 attached to the sleeve tube 11, a fixed lever 13 attached to the sleeve tube 11, elastic rings 14 connected to the operating lever 12 and the fixed lever 13, respectively, and a bag body 15 to which the elastic ring 14 is attached and which moves in conjunction with the elastic ring 14.

[0003] During use, when the operating lever 12 is pushed, the elastic ring 14 moves away from the sleeve tube 11, allowing the opening of the bag body 15 to be opened by its own elastic recovery force. To close the opening, the operating lever 12 is pulled back, causing the elastic ring 14 to be compressed by the sleeve tube 11, thereby reducing the size of the opening. However, when closing the opening, the elastic ring 14 constantly maintains its arc shape due to its own elastic recovery force, so although the opening can be reduced in size, it cannot be completely sealed. Furthermore, when the elastic ring 14 enters the sleeve tube 11, the bag body 15 is not contained within the sleeve tube 11 but is rolled up outside the opening of the sleeve tube 11, creating multiple wrinkles at the opening, making it even more difficult to seal.

[0004] The bag body 15 is used to store samples cut off during surgery, but most samples are usually from diseased tissue or parts of organs, and therefore contain blood or tissue fluids. If the sample or the fluids on it leak from the bag body 15 and come into contact with other parts of the patient, there is an increased risk of spreading pathogens or contamination.

[0005] 3 to 5 show the sample bag described in Patent Document 2. This conventional sample bag includes a sleeve tube 11, an operating lever 12 attached to the sleeve tube 11, a bag body 15, a deformable lever 16 connected to the operating lever 12, and a fixed lever 17 connected to the sleeve tube 11 and parallel to the deformable lever 16. The deformable lever 16 and the fixed lever 17 are attached to the bag body 15, and when the operating lever 12 pushes the deformable lever 16 outward from the sleeve tube 11, the tip of the deformable lever 16 abuts against the fixed lever 17, thereby bending the deformable lever 16 and opening the opening of the bag body 15. When closing the opening of the bag body 15, this sample bag aligns the deformable lever 16 parallel to the fixed lever 17 and moves them closer together, thereby closing the opening and eliminating the bending angle, thereby solving the problem of incomplete closure of the opening.

[0006] However, as described above, the tip of the deformable lever 16 is directly abutted against the fixed lever 17, causing the deformable lever 16 to buckle and open the opening of the bag body 15. If too much force is applied to the deformable lever 16 at this time, the deformable lever 16 is likely to deform unpredictably. Furthermore, because the configuration of the tip of the deformable lever 16 is not limited to the fixed lever 17, it is also easy for the deformable lever 16 to separate from the fixed lever 17 and cause the opening of the bag body 15 to unexpectedly open. If the sample or liquid on it leaks out of the bag body 15 and comes into contact with other parts of the patient, the risk of spreading pathogens and contamination increases, a problem that has not yet been completely resolved.

[0008] Therefore, an object of the present invention is to provide a sample holding device for minimally wound surgery that reduces the risk of contamination. [Means for solving the problem]

[0009] In view of the above problems, the present invention provides a device including: a housing means extending along a front-rear direction; an opening / closing means disposed on the housing means, the opening / closing means having an operating lever movably disposed on the housing means, a fixed lever interlocked with the operating lever, and a deformable lever inseparably connected to one end of the fixed lever; A sample storage device for minimum incision surgery, comprising: a sample bag having an inlet attached to the fixed lever and the deformable lever of the opening / closing means and interlocking with the opening / closing means, and connected to the opening / closing means; We provide a sample storage device for minimum incision surgery, characterized in that the operating lever can be moved along the forward / backward direction, so that the fixed lever and the deformable lever are adjacent and parallel, and can be switched between a closed position in which the inlet of the sample bag is closed, and an open position in which the deformable lever is bent to open the inlet of the sample bag. [Effects of the Invention]

[0010] In the present invention, the fixed lever and deformable lever of the opening / closing means are inseparably connected to each other, and in the closed position where the sample bag opening is closed, the fixed lever and deformable lever are adjacent and parallel, so that the sample bag opening can be closed reliably and a situation where excessive force causes the deformable lever and fixed lever to separate from each other and open the sample bag opening does not occur, thereby reducing the risk of contamination due to the sample bag opening not being securely closed.

[0012] Before proceeding to the specific description, it should be noted that components that play the same role in the present invention are assigned the same reference numerals even if they are not exactly the same. Furthermore, terms such as "front," "rear," "left," and "right" in the following description are used to clearly explain the relative positional relationships between the components, and do not limit the configuration of the present invention. The present application will be described in detail below with reference to the drawings.

[0013] First, Figures 6 to 9 show a first embodiment of the sample storage device for minimum incision surgery of the present invention, and as shown, the sample storage device for minimum incision surgery of the present invention has a housing means 2, an opening / closing means 3, and a sample bag 4.

[0014] The housing means 2 extends along the front-rear direction X, and has a first casing 21, a second casing 22 connected to the first casing 21, an accommodation space 23 surrounded by the first casing 21 and the second casing 22, a guide groove 24 that penetrates the housing means 2 in the left-right direction Y perpendicular to the front-rear direction X and extends along the front-rear direction X so as to connect the accommodation space 23 to an external space, and an extension pipe 25 that is detachably connected to the first casing 21 and the second casing 22. Furthermore, the first casing 21 and the second casing 22 can be configured to be detachably connected to each other.

[0015] 8 to 10 , the first casing 21 has a first surrounding portion 211 that surrounds the housing space 23 together with the second casing 22, a holding portion 212 that protrudes from the first surrounding portion 211 toward the second casing 22 and extends along the front-rear direction X, and a first extending portion 213 that extends along the front-rear direction X. The first surrounding portion 211 has a first end wall 214 and a second end wall 215 located at both ends in the front-rear direction X, a first surrounding wall 216 that extends to connect the first end wall 214 and the second end wall 215, and a communication hole 217 that penetrates the first end wall 214. The first extending portion 213 extends from the first end wall 214 to the opposite side of the second end wall 215.

[0016] The second casing 22 has a second surrounding portion 221 that, together with the first surrounding portion 211, surrounds the storage space 23, and a second extending portion 222 that extends along the front-rear direction X. The second surrounding portion 221 has a third end wall 223 and a fourth end wall 224 located at both ends in the front-rear direction X, a second surrounding wall 225 that extends to connect the third end wall 223 and the fourth end wall 224, and a limiting groove 226 that penetrates the second surrounding wall 225 and connects the storage space 23 to the outside space. The second extending portion 222 extends from the third end wall 223 to the opposite side of the fourth end wall 224, and, together with the first extending portion 213, surrounds a sleeve slot 227 into which the extension pipe 25 is fitted. The limiting groove 226 has one engagement area 228 on each side extending in the front-rear direction X, and is formed in the shape of a "mountain."

[0017] The first casing 21 and the second casing 22 are assembled into a single cylindrical shape, and the storage space 23 inside the first casing 21 and the second casing 22 is surrounded by the first end wall 214, the second end wall 215, and the first surrounding wall 216 of the first surrounding portion 211, and the third end wall 223, the fourth end wall 224, and the second surrounding wall 225 of the second surrounding portion 221. Recesses are formed on both the left and right sides of the first surrounding wall 216 and the second surrounding wall 225 in the up-down direction, respectively, to form one guide groove 24 on each side when assembled into a cylindrical shape. A wide area 242 (see FIG. 6 ) is formed in the guide groove 24 in the front-rear direction X, corresponding to the position of the limiting groove 226. The portion other than the wide area 242 becomes a narrow area 241 whose width in the up-down direction Z is narrower than that of the wide area 242. The extension pipe 25 surrounds a receiving space 251 capable of accommodating the sample bag 4, and when the extension pipe 25 is fitted into the sleeve slot 227, the accommodation space 23 and the receiving space 251 communicate with each other via the communication hole 217 penetrating the first end wall 214. That is, the extension pipe 25 can be detachably connected to the first casing 21 and the second casing 22, and when connected to the first casing 21 and the second casing 22, the extension pipe 25 communicates with the accommodation space 23 and surrounds the receiving space 251 capable of accommodating the fixed lever 33, the deformable lever 34, and the sample bag 4.

[0018] The opening / closing means 3 is attached to the housing means 2 and has an operating lever 31 movably attached to the housing means 2, a separation lever 32 removably connected to the operating lever 31, a fixed lever 33 removably connected to the separation lever 32 and moving in conjunction with the operating lever 31, and a deformable lever 34 inseparably connected to the fixed lever 33.

[0019] The operating lever 31 has a main body 311 arranged within the accommodation space 23 so as to be movable along the front-rear direction X, two handle portions 312 exposed to the external space from the main body 311 along the left-right direction Y via respective guide grooves 24, a connecting protrusion 313 extending from the main body 311 in the up-down direction Z, and an insertion portion 314 protruding from the main body 311 in the up-down direction Z and formed so as to be able to be inserted into the limiting groove 226. In addition, an insertion slot 315 is formed on the side of the main body 311 facing the first end wall 214, which is recessed in the front-rear direction X and into which the separation lever 32 can be inserted.

[0020] In this embodiment, the number of handle portions 312 is two, but there is no particular limit to the number of handle portions 312, and it is possible to use just one. Furthermore, when the handle portion 312 passes through the guide groove 24 and reaches the wide area 242, it can move in the up-down direction Z together with the operating lever 31. In addition, in this embodiment, there is no particular limit to the shape or number of the fitting portion 314 formed on the operating lever 31, and it is sufficient that it can be fitted into the limiting groove 226 to limit the movement of the operating lever 31 in the front-rear direction relative to the housing means 2.

[0021] 8, 9, and 12, the separating lever 32 has a hook portion 321 extending in the up-down direction Z. The holding portion 212 of the first casing 21 extends from the first end wall 214 to a predetermined position approximately in the center between the first end wall 214 and the second end wall 215. This predetermined position means that the distance from the end of the holding portion 212 facing the first end wall 214 to the first end wall 214 is approximately the same as the entire length of the separating lever 32 in the front-rear direction X, and the separating lever 32 can be accommodated in the space from the end of the holding portion 212 facing the first end wall 214 to the first end wall 214.

[0022] Both the fixed lever 33 and the deformable lever 34 are formed in the shape of a long, thin rod. The fixed lever 33 is shorter in length in the front-rear direction X than the deformable lever 34 and is thicker than the deformable lever 34. One end of the fixed lever 33 in the front-rear direction X is attached to the hook portion 321 of the separation lever 32 as an attachment end 331, and the other end is inseparably connected to the deformable lever 34 as a first rotational coupling end 332. One end of the deformable lever 34 in the front-rear direction X is removably connected to the connection protrusion 313 of the operating lever 31 as a fixed end 341, and the other end is inseparably connected to the first rotational coupling end 332 of the fixed lever 33 as a second rotational coupling end 342. Incidentally, the phrase "inseparably connected to each other" used here means that the first rotational coupling end 332 and the second rotational coupling end 342 remain connected to each other unless they are forcibly separated using an external force or the like. In this embodiment, the first rotary connection end 332 and the second rotary connection end 342 are wound around each other to allow a certain degree of relative rotation.

[0023] The sample bag 4 is formed in a bag shape with an inlet 41 that connects the internal and external spaces, and a fixed lever 33 and a deformable lever 34 are attached to the periphery of the inlet 41, so that the bag can be opened and closed by changing the shape and relative position of the fixed lever 33 and the deformable lever 34.

[0024] 10, 11, and 13, the opening / closing means 3 is configured so that, when operated via the handle portion 312 of the operating lever 31 and moved in the front-to-rear direction X, it can be switched between a closed position (see FIGS. 9, 11, and 12) in which the fixed lever 33 and the deformable lever 34 are adjacent to and parallel to each other, closing the inlet 41 of the sample bag 4, and an open position (see FIG. 13) in which the deformable lever 34 is curved to form a predetermined angle with the fixed lever 33, opening the inlet 41 of the sample bag 4. Incidentally, the limiting groove 226 is formed in a position where it can receive and engage with the fitting portion 314 of the operating lever 31 in this open position.

[0025] That is, as shown in FIG. 11 , when the main body 311 of the operating lever 31 is positioned toward the rear in the front-rear direction X (toward the second end wall 215 / fourth end wall 224), the fixed lever 33 and the deformable lever 34 are adjacent to each other in parallel, and the separation lever 32 connecting the operating lever 31 and the fixed lever 33 is sandwiched between the operating lever 31 and the holder 212. Therefore, the insertion opening 41 for the sample bag 4 is closed, and the internal and external spaces are isolated. Also, as shown in FIGS. 9 and 11 , when the main body 311 of the operating lever 31 is positioned closest to the second end wall 215 in the front-rear direction X, the sample bag 4 is accommodated in the receiving space 251 surrounded by the extension pipe 25 attached to the sleeve slot 227. At this time, the extension pipe 25 can be inserted into the body through an opening made by an incision during surgery, for example.

[0026] 9 and 11, the fixed lever 33 and the deformable lever 34 move forward together with the connected operating lever 31 and separating lever 32 while maintaining a mutually parallel state. However, when the separating lever 32 reaches the state shown in FIGS. 10 and 12, that is, when the separating lever 32, which is sandwiched between the operating lever 31 and the holding portion 212 and moves forward together with the operating lever 31, passes the predetermined position (i.e., moves away from between the holding portion 212 and the second casing 22) and is no longer supported by the holding portion 212, the separating lever 32 becomes housed in the space from the end of the holding portion 212 facing the first end wall 214 to the first end wall 214 and is separated from the operating lever 31 and the fixed lever 33. Since the separating lever 32, blocked by the first end wall 214, cannot move forward further together with the operating lever 31, the fixed lever 33 cannot move forward further together with the operating lever 31 either. In addition, as shown in FIG. 10, in this state, the sample bag 4 is pushed out from the extension pipe 25.

[0027] 10 and 12, when the operating lever 31 is further moved forward, the fixed end 34 of the deformable lever 34 2 The second rotation coupling end 34 of the deformed lever 34 moves forward together with the operating lever 31. 3 Since the first rotation connection end 332 of the fixed lever 33 is inseparably connected to the second rotation connection end 332 of the fixed lever 33, the fixed end 34 moves forward together with the operating lever 31 as shown in FIG. 2 is the second rotary connection end 34 3 , the deformation lever 34 is bent and deformed, and the insertion opening 41 of the sample bag 4 is opened by the deformation of the deformation lever 34. When the forward movement of the operating lever 31 causes the fitting portion 314 formed on the operating lever 31 to reach a position where it fits into the limiting groove 226, the operating lever 31 is moved in the up-down direction Z to fit the fitting portion 314 into the limiting groove 226, thereby restricting the movement of the operating lever 31 in the front-rear direction X, and the insertion opening 41 of the sample bag 4 can be kept in the open position where it is open even when the operation of the handle portion 312 is stopped.

[0028] 10 and 12, i.e., the closed position, by moving the operating lever 31 in the up / down direction Z to pull the fitting portion 314 out of the limiting groove 226 and then further pulling the operating lever 31 backward. This allows the sample bag 4 to be removed from the body with the inlet 41 of the sample bag 4 closed, thereby reducing the risk of contamination due to the sample bag being loosely closed. Furthermore, if the first casing 21 and the second casing 22 are configured to be detachably connected to each other, before removing the sample bag 4 from the body, the first casing 21 and the second casing 22 are first detached so as to separate them, and then the operating lever 31 and the separating lever 32 are also removed. This leaves only the fixed lever 33 and the deformable lever 34 connected to the sample bag 4 in the sample storage device for minimal incision surgery of the present invention, which has the advantage of reducing the overall volume and making the subsequent surgery easier.

[0029] As shown in Figures 14 and 15, the second embodiment of the sample storage device for minimum incision surgery of the present invention has a configuration similar to that of the first embodiment, but differs only in the configuration of the fixed lever 33, and this difference will be explained in detail below.

[0030] In this second embodiment, the fixed lever 33 of the opening / closing means 3 has a fixed extension member 335 having an attachment end 331 attached to the hook portion 321 of the separation lever 32, and a quick deformation member 333 connected to the fixed extension member 335 via a connecting member 334, having a first rotating connecting end 332, and connected to the second rotating connecting end 342 of the deformation lever 34.

[0031] In this second embodiment, the quick deformation member 333 has the same configuration as a so-called snap band that can be quickly switched between a straight-scale state and a tape measure state. In other words, in the straight-scale state, the quick deformation member 333 and the deformation lever 34 both extend along the front-to-back direction X, and when switched to the tape measure state, they bend toward the deformation lever 34, thereby bending and deforming the deformation lever 34, thereby opening the opening 41 of the sample bag 4.

[0032] In this second embodiment, the quick-deformation member 333 can be instantly switched from a straight-line state to a tape measure state by actuation via the fixed extension member 335 or by contacting the quick-deformation member 333 with another surgical instrument.

[0033] In this way, the second embodiment of the present invention can achieve the same effect as the first embodiment.

[0034] Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
