Further referring to the valve 133, the valve 133 is coupled to the cap portion 106 and is connected to the manifold volume. The cap portion 106 is disposed within a cavity that defines at least a portion of the cavity 108. In particular, the inner or proximal surface of the cap portion 106 may have a proximal extending projection or the like. The valve 133 may include a coupler 107 (see FIG. 10). 07.

A vacuum is applied to the cap 151a or through the manifold 100. If the inlet holes 114a, 114b are not sealed from fluid communication with the surroundings, The elastic deformation of the wing 139 of the trumpet 135 allows the wing 139 to bend in the proximal direction. To achieve this, a vacuum is drawn on or through the manifold 100. is sufficient. By moving the nozzle 135 away from the inlet bores 114a, 114b, the manifold volume 1 08 and thus a suction path leading to the suction inlet 58 is established. Upon stopping the vacuum pumping through manifold 100, valve 133 closes naturally or Returning to the unstressed state, the wings 139 resiliently move the flapper 135 to the cap portion 106 the inner or proximal surface of the entry perforation 114 and the transition perforation 125.

The holes 114a, 114b are provided to the suction inlet 58. The filter element 116 is 20 and at least one side wall 121 extending distally from said base wall 120. The porous mechanism may comprise a basket-like structure 119 that defines the mouth. It may be defined within the base wall 120, the side wall 121, and / or the flange 117 described below. To maintain the rotational orientation of the filter element 116 relative to the body portion 104, 16 and body portion 104 radially align filter element 116 within body portion 104. The device may include multiple features including ribs 115 configured to facilitate movement. The filter element 116 is in fluid communication with the outlet opening 110 of the manifold 100. The manifold 100 may be disposed in a location separate from the volume 108. The shape and configuration of the filter element 116 suitable for various applications is disclosed in the patent application filed on March 15, 2018. and commonly owned International Publication No. WO2018 / 170233, all of which Further, the filter element 116 is considered optional and the filter Manifold designs that do not include elements are also contemplated.

[0018] The filter element 116 may include a collar 117 coupled to a basket 119. The collar 117 may extend distally and radially outward from the basket 119. The flange 117 has an outer diameter or outer size larger than the outer diameter or outer size of the basket 119. 6 and 7, the length of the basket 119 is The length of the flange 117 may be set to be equal to or greater than the length of the main body 104. The inner surface of the neck 105 may be arranged in the neck 105 of the nozzle 104. , a step 109 extends radially inward. The filter element 116 has a protruding wall 116a that defines a portion of the flange 117. The resulting configuration is that when the body portion 104 is coupled with the cap portion 106, The basket 119 is secured within the manifold volume 108 by an interference fit. In other words, when assembling the manifold 100, the flange 117 of the filter element 116 is The cap 106 is positioned against the inner surface of the cap 106, and the body 104 is positioned against the back of the filter element 116. The main body 104 may be adapted to advance on a skid 119. The step 109 of the body portion 104 is coupled to the cap portion 106 and defines the proximal side of the collar portion 117. The filter basket 116 is axially moved within the manifold volume 108 by engaging the overhanging wall of the filter basket 116. As previously mentioned, the rib 11 engages with a slot (not shown) within the body 104. 5 radially aligns the filter element 116 within the body portion 104 .

[0019] The filter element 116, in its broadest sense, is a filter that is provided by the medical waste collection system 50. Semi-solid matter trapped in the liquid waste is pulled through manifold 100 under the influence of vacuum. The filter element 1 includes a structure configured to capture or collect solid waste. The 16 openings may be specifically shaped as holes, pores, and / or slots. The holes, pores, and / or slots are formed in the base wall 120, the side wall 121, and the collar 117. The openings may be defined in any one or more of the following ways: The filter element 116 is positioned to minimize clogging. For example, the slots defined in the sidewall 121 extend above the lower side of the filter element 116. Once collected, semi-solid or solid waste is transported by gravity. The waste accumulates at the bottom of the basket 119 under the influence of the wind, and the waste then flows through the top of the accumulation. Once a sufficient amount of semi-solid or solid waste has accumulated, the waste will encounter a slot. It is believed desirable to have a slot with an area that allows for a larger volumetric flow. while being approximately equal to the pore size (to capture semi-solid or solid waste of the same size as the pores). Furthermore, the vertical orientation of the slots is perpendicular to the suction path and is oriented in a direction parallel to gravity. Therefore, further accumulation of semi-solid or solid waste will not substantially affect the basket. At least part of the slot will remain unobstructed until the entire lot 119 is consumed by waste. thus maximizing the operational life cycle of the manifold 100.

[0020] The filter element 116 has at least one overfill opening ( The overfill opening may also include a valve (not shown) to minimize the operational cycle of the manifold 100. As explained above, semi-solid or solid waste is collected and When the liquid is sucked into the basket 119, it accumulates at the bottom of the basket 119 under the influence of gravity. proximal direction), semi-solid or solid waste accumulates on the base wall 120 of the basket 119. If sufficient semi-solid or solid waste is generated during a surgical procedure, The accumulated semi-solid or solid waste may have consumed the entire basket 119. In other words, most of the holes, pores, and / or slots in the filter element 116 Some or all of the overfill openings may be clogged with semi-solid or solid waste. The suction path can be routed through the overfill opening to the exterior of the basket 119. In other words, they are sized and positioned so that the fluid follows the path of least resistance. Due to well-understood principles of fluid dynamics, the suction path in the above scenario is 14a, 114b through the cap portion 106, and the basket 119 and the inner surface of the main body portion 104. and extends through an overfill opening in the body portion 104 between the openings 104 and 110 to an outlet opening 110, which will be described later. .

[0021] Referring now to FIG. 5, the cap portion 106 comprises a cap head 142 and a support frame. The support frame 143 is integrally formed with the cap head 142. The support frame 143 may be positioned distal to the cap head 142, The cap portion 106 generally defines the front portion of the manifold 100. The cap portion 106 includes the upper wall 103, the first The support frame includes a first inlet fitting 112a and a second inlet fitting 112b. An auxiliary sleeve 113 coupled to the frame 143 includes a first inlet fitting 112a. The head 142 includes a second inlet fitting 112b. The first inlet fitting 112a is Extending upward from the distal barrier 103 with the mouth perforation 114a extending through the distal barrier 103. The second inlet fitting 112b is connected to a second inlet bore 114b (referred to herein as a valve bore). With the cap head 142 having a through hole (also referred to as a through hole) extending through the cap head 142, 142 extending distally.

[0022] The housing of the manifold 100 also has an auxiliary opening 111 which leads to an auxiliary sleeve 113. The auxiliary sleeve 113 is provided between the upper barrier 103, the lower barrier 122, and the upper barrier 103. The wall 103 is at least partially defined by side barriers 123 extending between the wall 103 and the lower barrier 122. The auxiliary sleeve 113 may be attached to an end barrier 124 opposite the auxiliary opening 111. The auxiliary sleeve 113 may be further defined by a perforation 125 (referred to herein as a and an opening 158 extending through the cap faceplate 140. The manifold volume 108 is in fluid communication with the manifold volume 108 through the perforations 125. More specifically, the perforations 125 are A first end of at least one of the barrier 122 and the side barriers 123 and a manifold and a second end (eg, opening 158) that opens into the ring volume.

[0023] The manifold 100 is removably positioned within the auxiliary sleeve 113. The tray 176 includes a tissue collection cavity 182 and a The tissue collection cavity 182 defines a porous feature 186. When positioned within the sleeve 113, the porous feature 186 is in the suction path, The tray 176 is placed in the auxiliary sleeve 113 to collect the tissue sample. It further includes a sealing surface 155 configured for sealing engagement with the opening 111. In particular, the tray 1 76 defines a sealing surface 155 configured to contact the outer periphery of the auxiliary opening 111. More specifically, the upper barrier, the lower barrier, and the side barriers may have flanges. With the auxiliary opening 111 integrally defined by the walls 103, 122, and 123, the upper obstacle The wall, the lower barrier, and the side barriers 103, 122, 123 each have a sealing surface 155 at their end. The tray 176 is located within the auxiliary sleeve 113 and is configured to contact the sealing surface 1 With the auxiliary opening 111 covered by the medical waste collection assembly 50, the suction Suction is maintained through the draw path.

[0024] Once the collected tissue sample is ready for retrieval, the tissue sample is placed in the tissue collection cavity. When the tray 176 is disposed in the auxiliary sleeve 113, the tray 176 is slidably removed from the auxiliary sleeve 113. However, moving the sealing surface 155 out of sealing engagement with the auxiliary opening 111 Using the principles of fluid dynamics, a second suction path can be created: from the suction line to the auxiliary sleeve. 113 and the first suction path through the manifold volume to the outlet opening is reduced or eliminated. 111 to the auxiliary sleeve 113 and manifold volume In other words, the perforations 125 are connected to the first and second, common to both suction paths, and includes the fluid itself (e.g., air vs. liquid waste) and Depending on the relative resistance to the fluid in the first and second suction paths, the second suction path , when the tray 176 is slidably removed from the auxiliary sleeve 113, the auxiliary opening 111 and the auxiliary sleeve 113, containing a substantial volume flow of fluid (usually air) through the In known systems, the tissue sample is subjected to a volumetric flow of fluid and associated forces. The tissue sample may be swept along with the fluid flow and expelled from the tray. In another example, the manifold from the medical waste collection assembly may without the need to remove the card and / or interrupt the operation of the medical waste collection assembly. It may be desirable to "bleed off" or reduce suction through the first suction path, at least temporarily. Known systems do not adequately address this requirement.

[0025] The manifold 100 minimizes the chance of inadvertent loss of tissue samples. In this way, it is convenient to position the second suction path. provides sufficient suction to the second suction path so that the first suction path may be temporarily restricted or omitted. This is convenient because it ensures a volume flow.

[0026] 6 and 7, the housing of the manifold 100 includes an auxiliary sleeve. 113. In the broadest sense, the positioning mechanism The mechanism 145 is attached to the base 184 (also referred to herein as the screen surface) of the tray 176. ) and at least a portion of the lower barrier 122 that at least partially defines the auxiliary sleeve 113 The tray 176 is configured to be appropriately positioned so that a gap (G) is defined between the tray 176 and the As will be explained in more detail below, the gap (G) is the gap where the second suction path (SSP) is located. The gap (G) is closed by mechanical forces without encountering the tissue collection cavity 182 of the tray 176. By being guided through the tissue, the possibility of losing tissue samples is minimized. The illustrated positioning mechanism 145 is a plate that defines a trough 127 therebetween. It should be understood that the trough 127 is at least part of the auxiliary sleeve 113. The opening 111 also defines a portion of the opening 112 and extends to the auxiliary opening 111 .

[0027] 8 and 9 show a tray 176 having a base 184. As shown, The base 184 may be slightly arched, or alternatively, may be planar. The tray 176 may be of any suitable profile. The base and the side 185 (also referred to herein as the side surface) are formed on the base. Side portions 184, 185 extend from sealing surface 155 and define tissue collection cavity 182. Conventionally, the tissue collection cavity 182 has a flat surface with sides 185. The porous feature 186 is thought to be open in the longitudinal direction away from the base 184. is defined within the base 184.

[0028] The tray 176 includes one or more control surfaces configured to receive input from a user. 8 and 9 show the flanges in opposite directions from the sealing surface 155. The control surfaces 188a and 188b are shown extending from the The grip may be formed as a grip portion that is held by the user's fingers. The device has a first portion 188a and a second portion 188b arranged in a plane such that the user By pinching, the first portion 188a is detached from the second portion 188b for the function described below. The device may be configured to move the image data to the target image.

[0029] With the tray 176 removably coupled to the housing, as shown in FIG. (i) the sealing member 155 seals the auxiliary opening 111, and (ii) the tissue collection cavity 182 seals the auxiliary opening 111. (iii) a base member 112b positioned in the auxiliary sleeve 113 and communicating with the inlet bore 112a; The portion 184 and / or the side portion 185 engage the positioning mechanism 145 in the auxiliary sleeve 113. Thus, the aforementioned gap (G) is provided between the base 184 of the tray 176 and the lower barrier 122 . More specifically, a gap ( The base 184 of the tray 176 rests or rests on the plateau 147 as defined by arrow G. The gap (G) is located directly below the tray 176 (i.e., i.e., in the aforementioned convention, is considered to be opposite the tissue collection cavity 182). With the tray 176 positioned within the auxiliary sleeve 113, the manifold volume 10 The gap (G) communicates with the perforation 125 extending to the tray 176. It is positioned adjacent to the upper barrier 103 with very little space between them.

[0030] At least a portion of the sealing surface 155 may be formed from a resiliently flexible material. , the lower side of the sealing surface 155 (i.e., the lower side that at least partially defines the auxiliary opening 111 The side of the sealing surface 155 that contacts the end of the side barrier 122 is made of an elastically flexible material. The resiliently flexible material may be secured to the control surface 18 by, for example, gussets 129. 9, the gusset 129 defines a sealing surface 155. and a second portion 188b of the gripping portion that defines the control surface 188. It has a triangular structure.

[0031] In operation, the user installs the first inlet bore 114a, the auxiliary sleeve 113, and the bore If it is desired to reduce or eliminate the first suction path through 125, an input is provided to control surface 188. In particular, the user presses first and second portions 188a, 188b of the grip portion, which define the control surface 188. 6 and 7, first portion 188a The manifold 100 is moved or pivoted (P) toward the second portion 188b. The flange defining the sealing surface 155 is resiliently deflected to move from the sealing configuration to the flow-through configuration. The rigid connection from the flexible material and gusset 129 allows the auxiliary opening 124 near the lower barrier 122 to be At least a portion of the sealing surface 155 is spaced apart from the portion 11. The trough 127 is exposed to the atmosphere and provides a second suction path (SSP). Thus, the second suction path (SSP) passes through the base 184 of the tray 176 and the auxiliary sleeve 113. From the auxiliary opening 111 through the gap (G) between the lower wall 122 of the housing defining The end of the suction line is positioned well upstream of the surgical site. The resistance of the fluid (e.g., air) entering the second suction path (SSP) is low relative to the (and the density of the waste in the suction line relative to the air) will cause a second The suction path (SSP) is the primary suction path in the outflow configuration, and the suction line 52 Negligible suction may be maintained. The user may choose to use the First Suction Path (FSP) as the primary (and only) If one wishes to quickly re-establish the suction path, one simply releases the input provided to control surface 188. The elasticity of the sealing surface 155 and the second suction path (SSP) adjacent to the sealing surface 155 This causes the sealing surface 155 to re-engage the auxiliary opening 111, thereby sealing the manifold 100. Moving the manifold 100 between the sealing and outflow configurations can be extremely as many times as necessary without difficulty and without stopping the operation of the medical waste collection assembly 50. It is Noh.

[0032] Additionally, as previously mentioned, the second suction path (SSP) is located below the tray 176 (i.e., In the above-mentioned convention, the tissue collection cavity 182 is located opposite the tissue collection cavity 182. As such, if the user wishes to retrieve the tissue sample collected in the tissue collection cavity 182, In this case, the tray 176 is pulled out of the auxiliary sleeve 113 while maintaining input to the control surface 188. Any distance from the upper side of the tray 176 positioned adjacent to the upper barrier 103 Since the gap (G) is relatively larger than the distance, when removing the tray 176, The second suction path (SSP) remains almost entirely below the tray 176. While the tissue is being collected, a second suction travels over the tray 176 and is drawn into the tissue collection cavity 182. Any flow of fluid in the path (SSP) can be ignored. As a result, the user can without the risk of compromising critical aspects of the surgical procedure by inadvertently losing tissue samples. -176 can be extracted reliably.

[0033] 8 and 9, the tray 176 includes a foot 131 extending from a base 184. Specifically, the tissue collection cavity 182 includes a foot 131 extending from a base 184 in a direction opposite the tissue collection cavity 182. The foot 131 is generally U-shaped and is a porous structure of the base 184 when viewed from the bottom. 186 (see FIG. 9). Alternatively, the foot 131 may be, for example, a side It may also be a series of discontinuous projections extending from base 184 near 185. However, the generally U-shaped foot portion 131 is configured so that the entire tray 176 is positioned within the auxiliary sleeve 113. If so, the boundary of the perforations 125 in communication with the manifold volume 108 may be shown. In other words, each side of the foot 131 rests on one of the plateaus 147. and a foot 131 near the end barrier 124 opposite the auxiliary opening 111. The distal portion of the foot 131 may be supported by the lower barrier 122. The relatively minimal gaps (particularly with the boundary definition of the perforations 125) allow for the formation of a porous structure 1 86), when the manifold 100 is in the outlet configuration, a second suction path ( This configuration substantially isolates the first suction path (FSP) from the second suction path (SSP). When the field 100 is in the outflow configuration, the second suction path (SSP) and the first suction path (FSP) ) and the resistance difference between the first and second suction paths (SSP) becomes larger, so the second suction path (SSP) becomes the outflow configuration. so that negligible suction is maintained in the suction line 52. It may be so.

[0034] The foot 131 also positions the base 184 of the tray 176 within the auxiliary sleeve 113. More specifically, the foot portion 131 may be configured as a plateau, as described above. 147 or may be positioned adjacent to the plateau 147. Another gap is provided between the base 184 and the lower barrier 122 that defines a gap (G). FIG. 7 shows the gap (G) between the base 1 of the tray 176 and the plateau 147. 8 shows the distal portion of foot 131 resting on lower barrier 122 as it extends to 84. The size of the gap (G) (i.e., the distance from the base 184 defining the trough 127 to the lower barrier 122 By maximizing the distance to the outlet, the outflow function becomes more effective and the second intake The fluid in the drainage path (SSP) flows over the tray 176 and collects the tissue samples. This further reduces the likelihood of rejection or excretion.

[0035] With continued reference to FIGS. 8 and 9, the tray 176 is configured to accommodate the complementary orientation of the auxiliary sleeve 113. 4, specifically to allow the tissue collection cavity 182 to engage the upper barrier 103. The tray 176 is supported by the auxiliary slide 176 in a single relative orientation with respect to the upper barrier 103. An orientation mechanism 187 configured to position within the sleeve 113 may be included. The orientation mechanism 189 of the auxiliary sleeve 113 may be a groove defined in each of the side walls 123. In other words, the two side walls 123 are each stretched outward near the upper wall 103. The tray 176 has an orientation mechanism 187 that defines a groove. Rails extending from the side 185 near the upper side are contemplated. 9 may be configured to be movably engaged by sliding of the rail within the groove. The orientation feature 187 of the tray 176 adjusts the vertical orientation of the base 184 relative to the lower barrier 122. The positioning determines the size of the gap (G) at least in part by defining the position. It will be appreciated that the device may also function as a locking mechanism.

[0036] In certain embodiments, the cap portion 106 and the body portion 104 are removably attached to each other. 3 to 5, the cap portion 106 is at least one of the main body portion 104 and the cap portion 106 is connected to each other. configured to be removably coupled with one of the keyways 148 or the fuselage coupler. The head coupler includes at least one key 146. The key 146 is diametrically spaced apart from the head coupler. There may be two keys 146 that face each other and extend proximally from the cap portion 106 . The keyways 148 are diametrically opposed to one another and extend radially outward from the neck 105 of the body 104. There may be two keyways 148 defined between at least one extended lip 149. In another embodiment, the key 146 and keyway 148 are each angled approximately 120 degrees from one another. There may be three spaced apart keys 146 and three keyways 148. The keyways 148 are The device may include an insertion portion 152 and a locking portion 153 that communicates with the insertion portion 152. As best shown in FIG. 11, the insertion portion 152 may be wider than the locking portion 153. Then, the portion of the lip 149 that defines the locking portion 153 comes into contact with the portion of the lip 149 that defines the insertion portion 152. The key 146 may be thinner than the portion 49. The key 146 has a leg 162 and a portion extending from the leg 162. The barb 164 may be thicker than the leg 162. The width of the portion 152 is greater than the thickness of the barb 164 and greater than the thickness of the leg portion 162. The width of the locking portion 153 is smaller than the thickness of the barb 164 and is larger than the thickness of the leg portion 162. Additionally, the length of the legs 162 may be at least equal to the length of the lip 149. More specifically, the length of the leg 162 is the length of the portion of the lip 149 that defines the insert 152. The length of the legs 162 may be greater than the length of the lip 149 that defines the stop 153. As a result, when assembling the manifold 100, If it is desired to couple the cap portion 106 to the body portion 104, the cap portion 106 may be The insert 152 is rotated relative to the main body 104 so that the insert 164 is aligned with the insert 152 in the rotational direction. A barb 164 extends through the insert 152, past the lip 149, and toward the leg. The cap portion 106 is positioned on the main body portion 104 side so that the portion 162 is positioned within the insertion portion 152. The cap portion 106 moves clockwise in FIG. Rotation relative to the leg 162 moves the key 146 within the keyway 148. The portion of the lip 166 that defines the locking portion 153 and the barb 164 are positioned in an interference arrangement. In this state, the insertion portion 152 moves into the locking portion 153. The cap portion 106 is fixed to the main body portion 104 to prevent axial movement of the cap portion 106. These components may be considered to constitute the housing 102 of the manifold 100.

[0037] The removable connection between the cap portion 106 and the body portion 104 allows the filter element 116 is accessible to the manifold volume 108 in which it is disposed. Among other things, access to the filter element 116 allows the user to: Waste matter (most notably polyps or tissue fragments) collected in the filter element 116 The samples can be collected for further testing and processing. Published and co-owned International Publication No. WO2013 / 090579 discloses methods for treating polyps or tissue The manifold includes a tissue trap for collecting samples, all of which In certain embodiments, the manifold 100 (cap portion 106) may include other mechanisms to facilitate collection of tissue samples.

[0038] If it is desired to separate the cap portion 106 from the body portion 104, the method steps described above may be repeated. The cap portion 106 rotates counterclockwise in FIG. 11 relative to the main body portion 104. Rotation of the legs 162 moves the key 146 within the keyway 148. With barb 164 removed from interference with the portion of lip 149 that defines stop 153 In this state, the cap portion 106 moves from the inside of the locking portion 153 to the inside of the insertion portion 152. 4 moves away from the body portion 104 so as to pass the lip 149, and the key 146 moves into the keyway 14 5, the cap portion 106 is disengaged from the cap 8. Access to the cavity 130 and / or manifold volume 108 of the body portion 104 Access is possible.

[0039] In certain embodiments, the cap portion 106 and the body portion 104 are connected by a suitable connecting process. are rigidly connected by means of a bonding agent (e.g., spin welding, solvent bonding, adhesive, mechanical fastening, etc.) As mentioned above, the housing 102 is made of a single piece so that the head and the body do not come apart. A preferred manufacturing process for constructing the housing 102 includes: In particular, injection molding, 3D printing, computer numerical control (CNC) machining, polymer casting, Suitable materials for constructing the housing 102 include: These include polymers, composites, metals, ceramics, and combinations thereof.

It is considered suitable for

[0040] 12-14, which are similar in at least some respects to those described above. 10 shows another similar manifold 200 (certain like components are numbered the same). (The figure shows the number 0 added.) The manifold 200 is detachably connected to the manifold receiver 54. The housing 202 is configured to be engaged with the It comprises a body portion 204 and a cap portion 206 coupled to the body portion 204. As best shown, the housing 202 defines a manifold volume 208 and the manifold. The body portion 204 defines an outlet opening 210 in fluid communication with the proximal base portion 208. 26 and extending distally from the proximal base 226 to include a portion of the manifold volume 208. and a side 228 defining a cavity 230. The exit opening 210 may include a proximal The cap portion 206 may be positioned within the base portion 226. 8. The drip valve 23 includes an inlet fitting 212 defining an inlet bore 214 in fluid communication with the drip valve 23. 2 may be disposed within the outlet opening 210 as described above.

[0041] 15-17 show a cap assembly including a cap faceplate 240 and a cap head 242. 206 is shown. The cap head 242 may be coupled to the body portion 204. The cap head 242 may include an annular beveled surface that terminates in an annular plateau 246. The annular beveled surface 244 is formed to facilitate proper assembly when the body and cap portions 204, 206 are assembled. The flange 248 of the body 204 is shaped to transmit elastic deflection. The return mechanism 250 passes through the annular plateau 246 and resiliently deflects outward. The cap head 242 is guided within the cap head 242 until it comes into interference engagement with the toe 246. In this configuration, the body and cap portions 204, 206 are generally prevented from separating. Additionally, the cap head 242 may include one or more orientation features 252 (e.g., annular inner surface The ribs may be formed on the flange 248. to prevent rotation of the cap head 242 relative to the body portion 204. The ribs receive tabs 227 of the filter element 216 to secure the filter to the cap portion 206. Rotation of the rotor element 216 may be prevented.

[0042] The cap head 242 has at least one distally extending cap 242 terminating at a distal face 256. The cap head 242 has a side wall 254. An opening 258 is formed through a distal face 256 of the cap head 242. The cap head 242 extends distally from the distal face 256 and defines a cavity 262 and a spindle 260 defining a coupling mechanism 264. The coupling mechanism 264 is 266 of the top plate 240. The complementary coupling mechanism 266 of the cap faceplate 240 is a pair of slots received in the slots. The complementary coupling mechanism 266 is a post arranged circumferentially to accommodate the spindle. radially from a tubular portion 268 configured to be received within the cavity 242 of the The cap face plate 240 has a proximal surface 270 and a distal surface opposite the proximal surface 270. The tubular portion 268 may be disc-shaped, including a proximal surface 272. The tubular portion 268 may extend proximally from the proximal surface 270. The cap head 242 and the cap face plate 240 are removably coupled to each other. To facilitate separation, the cap faceplate 240 may be manipulated (e.g., squeezed) by the user. The gripping portion 274 may be configured as follows.

[0043] The cap face plate 240 of the cap portion 206 includes the inlet fitting 212. Thus, the inlet fitting 212 is fitted with the inlet bore 214 extending through the cap faceplate 240. , extending distally from the distal surface 272 of the cap faceplate 240. As a result, the manifold When the hood 200 is assembled, the inlet fitting 212 is rotatable relative to the body 204. is fixed at

[0044] During operation of the medical waste collection assembly 50 with the manifold 200, the filter element The porous feature 218 of 216 allows tissue samples to be collected. Retrieval of tissue samples from the manifold 216 can be cumbersome. The manifold 200 allows for efficient collection of tissue samples from the manifold 200, and In addition to efficient collection of multiple tissue samples, the present invention also provides a method for eliminating the need for collection of tissue samples (i.e., This is advantageous because it allows selective operation of the system (without replacing components). 13, the manifold 200 is rotatable relative to the housing 202. 19, the tray 276 includes: A central lumen sized to receive the spindle 260 of the cap head 242 The tray 276 defines a spindle 280. The tray 276 is rotatably disposed about the spindle 260. In this state, the cap face plate 240 and the cap head 242 are in contact with each other, and the cap face plate 240 The cap head 242 is positioned between the proximal surface 270 of the cap head 242 and the distal surface 256 of the cap head 242. The tray 276 may be a single component or may be constructed from multiple components to form a tray assembly. The tray 276 may be attached to the housing 202 in a manner other than rotatable. The suction cup 11 may be movably disposed within the suction cup 11.

[0045] The tray 276 defines a plurality of tissue collection cavities 282. 82 may each extend at least partially through the tray 276. 6 further defines a porous feature 286 in each tissue collection cavity 282. Although four tissue collection cavities 282 are shown, the tray 276 does not include the tissue collection cavities 28 It is contemplated that the tissue may have one, two, three, five, six or more of the above. The collection cavities 282 are angularly spaced about an axis A that extends coaxially through the tray 276. Alternative configurations of the trays 276 may be unevenly spaced or a combination of evenly and unevenly spaced. The tissue collection cavities 282 may be arranged in a uniform manner in the tray 276. Although shown as an integrated unit, it is also shown as a modular insert for tray 276. The tray 276 may be configured to receive input from a user. 19 is realized by a central lumen 280 and an annular outer surface 290 opposite. A control surface 288 is shown that is qualitatively defined and provides a generally cylindrical shape to the tray 276. Input to surface 288 rotates tray 276 about axis A, thereby allowing tissue collection. One of the cavities 282 is selectively in fluid communication with the inlet bore 214, thereby allowing the porous material to The structure 286 is positioned in the suction path to allow tissue samples to be collected during operation of the medical waste collection assembly 50.

[0046] The distal face 256 of the cap head 242 may define the aforementioned opening 258 . The cap faceplate 240 is attached to the cap with the inlet bore 214 aligned with the opening 258. The tray 276 is rotatably fixed to the top head 242. and opening 258. The user inserts the tissue collection cavity 2 If one wishes to collect a tissue sample at one of the tissue samples 82, input is provided to control surface 288 to initiate the tissue sample collection. By moving (i.e., rotating) the 276 about axis A, the tissue collection cavity 282 is aligned with the entrance perforation 214 (and opening 258). The collection cavity 282 is located in the suction path and collects tissue samples being drawn through the suction path. The sample encounters a porous feature 286 within the tissue collection cavity 282. If a roll is desired, the user simply provides another input to control surface 288 to roll tray 276. By rotating about axis A, another tissue collection cavity 282 is formed between the entrance fenestrations 214. This method may be repeated for each tissue collection cavity 282. It may be configured to be returned.

[0047] For various reasons, users may choose to wait until a certain point in the surgical procedure and then 00 to collect tissue samples while for other reasons (e.g., visualization) You may want to maintain the ability to blot the surgical site. Additionally, the tissue samples are collected Thus, the user can perform the procedure in the surgical area without first having to retrieve the tissue sample from the manifold 200. You may want to continue suctioning data from the past for any period of time. Directing the flow over a contaminated tissue sample may also degrade the tissue sample itself. Manifold 200 is advantageous because it addresses the above-mentioned considerations. Referring again to FIG. In light of this, the tray 276 has at least one bypass cavity 282 separate from the tissue collection cavity 282. The bypass channels 292 each define a pair of bypass channels 292. ... The illustrated embodiment may be shaped as a four bar. Although the bypass channel 292 is shown, the tray 276 may have one or two bypass channels 292. It is contemplated that the tissue collection cavity 2 may define 3, 5, 6 or more tissue collection cavities. 82 and bypass channels 292 are alternately and equally angularly spaced about axis A. In an alternative embodiment of the tray 276, the tissue collection cavity 282 and / or The bypass channels 292 may be grouped and may be unequally spaced. Alternatively, the trays 276 may be spaced at regular intervals and at irregular intervals. A bypass channel 292 is defined between the outer surface of the tray 276 and the inner surface of the housing 202. It is contemplated that the tissue collection cavity 282 may be formed to define only the tissue collection cavity 282 in the assembled state. For example, the tray 276 may be triangular in shape and define a tissue collection cavity 282. The inner surface of the housing 202 circumscribes this triangle, and the triangular tray 276 The area between the inner surface of the housing 202 defines a bypass channel 292 .

[0048] During operation of the medical waste collection assembly 50, the tray 276 rotates about axis A to By selectively aligning the bypass channel 292 with the inlet bore 214 and the opening 258 This allows fluid to flow through the manifold 200 without collecting a tissue sample. In particular, a user may provide input to control surface 288 to rotate tray 276 about axis A. By rotating, one of the bypass channels 292 is aligned with the inlet bore 214 and the opening With the bypass channel 292 in the suction path, , the tissue collection cavity is not in the aspiration path and the flow does not encounter the porous feature 286. Thus, when the bypass channel 292 is in fluid communication with the inlet fenestrations 214, the tissue collection It is contemplated that cavity 282 is not in fluid communication with inlet bore 214. Whether or not tissue samples are collected by tray 276, manifold 20 The zero filter element 216 provides flow filtering.

[0049] The tray 276 of the manifold 200 is configured to accommodate the angular position of the tissue collection cavity 282. An alignment mechanism 294 may be included that is configured to provide a visual cue to the user. 19 and 20 show tabs extending radially from the annular outer surface 290 of the tray 276. Alignment feature 294 is shown in FIG. 1. Alignment feature 294 extends through axis A. , tissue collection cavity 282 are shown as being coplanar with the plane that bisects each of them. The alignment mechanism 294 also adjusts the alignment of the control surface 288 when applying an input to the control surface 288. Advantageously, the alignment mechanism 294 may function to improve operation of the device. , and control the input until one of the surface 288 (and / or alignment feature 294). 2 is aligned with the inlet bore 214, a pair of opposing alignment features 294 The gripping portion 274 is flush with the distal surface 22 of the cap face plate 240. This additional alignment provides the user with visual confirmation. Additional or alternative markings may be provided at suitable locations on the manifold 200. It is contemplated that the tray 276 may be configured to facilitate accurate orientation of the tray 276.

[0050] The manifold 200 expands in one or more of the tissue collection cavities 282. 296 positioned to provide a Referring to FIG. 18, the lens 296 is disposed on the cap face plate 240 of the cap portion 206. The lens 296 is positioned adjacent to the inlet fitting 212 and is in contact with the inlet bore 214. Visualize within the fluid-connected tissue collection cavity 282. In another embodiment (see FIG. 20), In this case, the lens 296 is disposed on the tray 276. The lens 296 is often on the order of micrometers, and the tissue collection cavity 282 With expansion occurring in one or more of the tissue collection cavities 28, the user More efficiently and effectively determine if sufficient tissue samples have been collected in one of two ways Illumination may be provided to illuminate one or more of the tissue collection cavities 282. It is contemplated that the manifold receptor 54 and / or the manifold 20 may be A light source (not shown) is suitably positioned at 0 to direct light into the tissue collection cavity 282. It may be designed to do so.

[0051] As previously mentioned, the bypass channel 292 allows the user to first without the need to retrieve tissue samples from the tissue sample collection site and without adequately checking the quality of the tissue sample initially collected. As a result, the manifold 20 can continue to suction the surgical site without interference. The surgical instrument can remain engaged with the medical waste collection assembly 50 until the end of the surgical procedure. The manifold 200 then facilitates efficient collection of the tissue sample. 206 is removably coupled to the tray 276 to form a tissue collection cavity. The user can then access the manifold 282 while holding the grip 274 in one hand. The user may hold the cap faceplate 240 and the cap 200 in the other hand. Complementary coupling mechanisms 266, 267 (for example, bayonet mounts) between the cap head 242 The gripping portion 274 is operated to disengage the cap head. The tissue collection cavity 282 is exposed by being separated from the cavity 242. The tray 276 is slidably removed from the spindle 260 of the cap head 242. This allows the user to simply manage the tray 276 during tissue sample collection. Additionally, the tray 276 is separable from the rest of the manifold 200 for easy collection. (e.g., placing a tray 276 containing tissue samples into a formalin container) It is envisaged that the tissue sample can be further processed.

The channel 295 is defined between the opposing surfaces and extends through the cap portion 206. The channel 295 has a width approximately equal to or greater than the diameter of the spindle 260. The width of the tray 278 provides a surmountable interference fit between the tray 278 and a portion of the central lumen 280. The diameter of the channel 295 may be slightly smaller than that of the spindle 260 so that the For example, the cap faceplate 240 can be mounted on the manifold 240 without having to be separated from the cap head 242. The tray 278 is separable from the rest of the 00.

FIG. 63 shows the auxiliary sleeve 913 in a state where it is tilted upward as will be described later. 9 shows auxiliary openings 911 positioned on the sides of the cap head 942'.

[0128] The manifold 900 is removably positioned within the auxiliary sleeve 913. 64, the tray 976 includes a tissue collection container 976. The tissue collection cavity 982 defines a porous feature 986 within the tissue collection cavity 982. With the roller 976 positioned within the auxiliary sleeve 913, the porous mechanism 986 It may be present in the pathway to collect tissue samples, as described above. The recovery of the collected tissue sample is further based on the rotatable position of the inlet perforation 914a. When desired, the tissue sample may be removed with the tissue sample disposed within the tissue collection cavity 982. The tray 976 can be slidably removed from the auxiliary sleeve 913 .

[0129] With continued reference to FIG. 64, the tray 976 includes a screen that defines a porous feature 986. The surface 984 may have a plurality of pairs of opposing sides 985 extending from the surface 984. The clean surface 984 integrally defines the tissue collection cavity 982 of the tray 976. The ray 976 includes a control surface 988 configured to receive input from a user. The surface 988 may be formed as a handle for a user's fingers to grasp. , configured to sealingly engage with housing 902 when received within auxiliary sleeve 913. In particular, the tray 976 contacts the outer periphery of the auxiliary opening 911. The tray may include a flange defining a sealing surface 955 configured to 976 is in the auxiliary sleeve 913 and the sealing surface 955 covers the auxiliary opening 911. Suction is maintained through the suction path during operation of the medical waste collection assembly 50. The sample is collected in the tissue collection cavity 982 and the user wishes to remove the tray 976. If a sufficient force input is applied to the control surface 988 of the tray 976, the tray 976 It is removed from the sleeve 913 .

[0130] Referring to FIG. 64, the tray 976 is configured to accommodate the complementary orientation of the auxiliary sleeve 913 (shown in FIG. 63). Engagement of mechanism 989 allows for a single relative orientation, specifically a predetermined orientation relative to upper barrier 903. an orienting mechanism 98 configured to position the tray 976 within the auxiliary sleeve 913; The tray's auxiliary sleeve 913 may further include an orientation feature 989. The tabs may be spaced apart from opposing barriers that at least partially define the auxiliary sleeve 913. 913 (for example, parallel to the upper wall 903) 63 shows the auxiliary opening 911 and the cap head opposite the auxiliary opening 911. 9 shows a tab extending only partially between an interface opening in a side wall 954 of door 942'. The orientation mechanism 989 is configured to substantially align the auxiliary sleeve 913 so as to approach the elongated rail. The orientation feature 989 may extend along the entire surface of the upper barrier 903. The auxiliary sleeve 913 is spaced closer to the distal barrier 903 than the barrier that at least partially defines the auxiliary sleeve 913. To separate the tray 976 from the housing 902, only one orientation is required. become.

[0131] The complementary orientation features 987 of the tray 976 movably engage with tabs on the auxiliary sleeve 913. 64 shows a rail configured to move from the sealing surface 955 to the sealing surface 955. 9 shows the rails extending outward to a position near the opposite end of the tray 976. Additionally, the orienting feature 987 has opposing sides that at least partially define the tissue collection cavity 982. The orientation feature 987 extends laterally outward from the upper edge of the side portion 985. In other words, it is positioned at the edge of the side 985 opposite the screen surface 984. The position of the alignment feature 987 relative to the line surface 984 and the alignment feature 98 relative to the upper barrier 903 The position of 7 requires that the tray 976 be inserted into the auxiliary sleeve 913 in a single orientation. The rails are threaded to the tissue collection cavity 982 so that the tissue collection cavity 982 opens into the first entrance bore 914a. The spring is movably engaged with the spring.

[0132] The orienting mechanisms 987, 989 are also located directly below the tray 976 (i.e., the tissue collection cavity). A positioning device (adjacent to the screen surface 984 opposite the tee 982) provides a second suction path. The auxiliary opening 911 may function as a sealing mechanism other than the sealing surface 955 of the tray 976. Therefore, the use of the second suction path reduces the distance between the inlet perforations 912a, 912b and the outlet opening. The suction ("outflow") between the two may be at least partially reduced or blocked. The attachment mechanism and the second suction path are described in more detail below. When the tray 976 is started to be removed from the sleeve 913, the corresponding The flow of fluid through the auxiliary sleeve 913 occurs in the path of least resistance. When the tray 976 is being removed from the tray 913, the second suction path is located directly below the tray 976. In this state, fluid flow through the auxiliary sleeve 913 is concentrated in the tissue collection cavity 982. This reduces the likelihood of inadvertent and unnecessary ejection of collected tissue samples. 987, 989 above the lower barrier that at least partially defines the auxiliary sleeve 913 The screen surface 984 may be raised to define the gap. An alignment feature 987 (e.g., a lens) is provided adjacent to the upper barrier 903 that at least partially defines the With the top surface of the tray 976 positioned, most of the fluid is guided directly below the tray 976. , so as not to come into contact with the tissue sample collected in the tissue collection cavity 982. It may be the path of least resistance. Negligible fluid flow enters the tissue collection cavity 982. In this condition, the forces involved are minimal and the collected tissue sample is firmly attached to the tissue collection cavity. The possibility of refrigerant being drawn off 82 and transferred to the manifold volume is reduced or eliminated.

[0133] The manifold 900 improves the user's tissue collection experience through visualization. 64, the tissue collection cavity 982 of the tray 976 is attached to the upper barrier 903. Thus, the manifold 900 accommodates the tissue collection when the tray is seated within the auxiliary sleeve 913. The auxiliary sleeve 913 is provided with a lens 996 that provides magnification within the collecting cavity. The barriers, such as the upper barrier 903, define a manifold. 900. The longitudinal axis of the rod 900 is oriented distally and superiorly. In particular, FIG. 63 shows the manifold 900 with its longitudinal axis The upper wall 903 on which the lens 996 is disposed is positioned at an angle γ with respect to the plane including the lens 996. The angle γ is about 10 to 45°, more specifically about 20 to 35°, and even more specifically The angle of the manifold 900 in the medical waste collection assembly 50 may be approximately 25°. Based on the orientation, the lens 996 is positioned in the manifold 900, which is oriented generally horizontally relative to the ground. The user can adjust the manifold 900 at a reasonable distance without excessive manipulation. manifold 900 from the outside to quickly verify that a suitable tissue sample has been captured. It is contemplated that lighting may be provided to illuminate the tissue collection cavity 982. do.
